A credit-card chargeback dispute letter should do four things: identify the exact posted transaction, explain the problem plainly, point to the records that support your account, and reach the correct issuer before the applicable deadline. The route changes when the payment came from a debit card, prepaid card, bank account, or payment app.

The information below is for U.S. consumers and is general information, not legal advice.

Start with the payment method

The funding source matters. A payment-app transaction funded by a credit card can involve both the app's case process and the card issuer's dispute process. A payment funded directly from a bank account may instead involve electronic-transfer or ACH procedures.

People often use “chargeback” as a catchall term. In practice, it's a request made through an issuer, bank, card network, or payment provider to reverse a payment. A merchant refund is different: it is a request to the seller for a credit. You can contact the merchant first, but don't wait for a response if the issuer's deadline is approaching.

The U.S. credit-card billing-error deadline

For many credit-card billing errors, the issuer must receive your written notice within 60 days after it sent the first statement containing the error. The clock generally starts with that statement, not the day you noticed the charge.

The Regulation Z billing-error rule covers examples such as:

• A transaction you didn't make or authorize
• The wrong charge amount
• A charge that isn't properly identified on the statement
• Goods or services that weren't accepted or weren't delivered as agreed
• A payment, refund, or other credit that wasn't posted correctly
• A calculation or accounting error

Send the notice to the address the issuer lists for billing-error inquiries. That address may be different from the address used for payments. The FTC's guidance on disputing credit-card charges recommends checking the back of the statement or the issuer's dispute instructions.

If you recently moved, there is an additional condition for using this federal billing-error process: the issuer generally must have received your written address change at least 20 days before the end of the billing period in question.

After receiving a timely notice, the issuer generally must acknowledge it in writing within 30 days unless it has already corrected the problem. It generally must finish the investigation within two complete billing cycles, and no later than 90 days. While the dispute is pending, pay the part of the bill that isn't disputed.

These rules don't guarantee a refund. The issuer reviews the transaction records, the merchant's response, your evidence, and the rule or procedure that applies.

Not every disappointing purchase is automatically a federal billing error. If the issue is a defect, a mismatch with an advertisement, or a contract disagreement, describe the specific promise and what the merchant did or failed to do. The issuer may review the matter under its card-network or internal dispute process rather than treating it as a qualifying Regulation Z billing error.

Credit-card dispute letter template

This template is for a credit-card billing-error notice. Replace the bracketed text, delete statements that don't fit, and send copies of your records rather than originals.

The FTC sample letter for disputing credit and debit card charges provides another format. If you're using the federal billing-error procedure, address the letter to the issuer's designated billing-inquiries department.

Re: Written notice of billing error
Account ending in: [last four digits]
Transaction date: [date]
Merchant: [merchant name as shown on statement]
Amount disputed: $[amount]

Dear Billing Inquiries Department:

I am writing to dispute a charge of $[amount] on my credit-card account. The first statement containing this charge was sent on [date].

I believe the charge is incorrect because [briefly describe what happened. For example:
the merchandise was not delivered;
I was charged twice for one purchase;
the receipt shows a different amount;
I returned the merchandise and the promised credit was not posted; or
I did not make or authorize this transaction].

I contacted [merchant name] on [date] by [email, phone, chat, or other method]. The result was [state the response or lack of response]. If you did not contact the merchant, briefly explain why, such as an unauthorized transaction.

Please investigate this billing error and correct my account. If the charge is found to be an error, please credit $[amount] and remove any related charges, as applicable. Please send me the investigation result and the explanation for your decision.

I will continue to pay the portion of my account that is not in dispute.

Enclosures:
1. Statement page showing the charge
2. [Receipt or order confirmation]
3. [Merchant messages or refund confirmation]
4. [Tracking, return, cancellation, or other supporting record]

Sincerely,

[Your name]

Give the issuer enough information to locate the account and transaction, but don't include an online-banking password, card security code, or full card number unless the issuer specifically requests it through a secure channel.

Examples for common dispute reasons

Use facts, dates, and amounts instead of relying on the word “fraud.” These examples are starting points, not guarantees of a successful dispute.

Unauthorized transaction

I did not make or authorize the transaction shown on my statement from [merchant] for $[amount] on [date]. I first noticed it on [date] and reported it to the issuer on [date]. Please investigate it as an unauthorized transaction.

Report suspected unauthorized activity to the issuer or bank immediately. If the card is missing, ask whether it should be blocked and replaced.

Merchandise or service not received

The merchant agreed to provide [item or service] by [promised date]. It was not delivered or provided. I contacted the merchant on [date], but [describe the response or lack of response]. The attached order confirmation and correspondence support this claim.

Include the promised delivery date and the carrier's status. If tracking shows delivery to the wrong address, say that directly.

Returned purchase or missing refund

I returned or canceled [item or service] on [date] under the merchant's stated policy. The merchant [confirmed or promised] a refund, but a credit of $[amount] has not appeared on my account. I have attached the return, cancellation, and refund records.

A written refund confirmation, credit memo, or return receipt is stronger evidence than a general statement that you expected money back.

Duplicate or incorrect amount

For a duplicate charge:

The same purchase appears twice on my statement, but I made only one purchase. The valid transaction is [identify it], and the duplicate is [identify it]. Please remove the duplicate charge.

For an incorrect amount:

My receipt and order confirmation show a total of $[correct amount], but the statement shows $[charged amount]. The difference is $[difference]. Please correct the amount.

Recurring charge after cancellation

I canceled the recurring service on [date] using [cancellation method]. The merchant confirmed the cancellation or provided cancellation instructions, but another charge of $[amount] appeared on [date]. Please review the attached cancellation record.

Cancel future recurring payments with the merchant and ask the issuer or bank whether it has a separate stop-payment or card-update procedure. Stopping a future payment does not by itself resolve an earlier charge.

Product or service not as described

The agreement or listing described [specific feature or condition], but what I received was [specific difference]. I contacted the merchant on [date] and requested [repair, replacement, or refund]. The attached description, receipt, photographs, and messages show the difference.

Be precise. Explain how the item or service differed from the agreement and what you did to resolve the problem. A general statement that you disliked the purchase gives the issuer little to investigate.

Records that make the timeline clear

A useful dispute file lets the reviewer understand what happened without reconstructing the story from scattered screenshots. Gather the records that fit your situation:

• The statement page showing the charge, with the transaction marked
• The merchant name, transaction date, amount, and order number
• The receipt, invoice, order confirmation, or service agreement
• The advertised delivery date, cancellation terms, or refund policy
• Emails, chat messages, customer-service ticket numbers, and call notes
• Shipping records, tracking information, delivery details, or return tracking
• A refund confirmation or credit memo
• Photographs showing damage or a material difference from the description
• Records showing when an unauthorized charge was reported
• A short chronology of the important dates and events

For example:

Number the attachments and refer to them in the letter: “See Attachment 2, the merchant's refund confirmation.” A few labeled documents are easier to review than dozens of unmarked screenshots.

For an unauthorized-transaction claim, state what you know and when you reported it. The issuer, merchant, or processor usually holds technical records such as authentication or address-verification data. You don't need to guess a card-network fraud code or invent technical evidence.

Sending the dispute

1. Make sure the charge is posted. A pending authorization is not the same as a completed charge. Ask the issuer what it can do with a pending amount rather than describing it as a posted billing error.

2. Identify the payment rail. Confirm whether the money came from a credit card, debit card, prepaid account, payment app, ACH transaction, or another bank transfer.

3. Contact the merchant when that makes sense. Ask for a refund or correction in writing and save the response. For an unauthorized transaction, contact the issuer or bank first.

4. Work out the deadline. For a credit-card billing error, use the date the first statement containing the error was sent. For debit cards, prepaid cards, payment apps, and bank transfers, ask the provider which deadline and form apply.

5. Send a complete written notice. If you're relying on the federal credit-card billing-error process, use the billing-inquiries address on the statement. A phone call alone may not preserve that written-notice process.

6. Keep delivery proof. Save the letter, attachments, mailing or delivery record, online upload confirmation, and case number. Keep the originals.

7. Pay the undisputed balance. Don't stop paying the entire credit-card bill because one transaction is under review.

8. Respond to follow-up requests. The issuer may ask for a receipt, statement, merchant correspondence, or signed declaration. Use the channel it specifies and send copies.

9. Read the final decision. Check the written result and a later statement to confirm whether the charge and any related amounts were corrected.

What can and cannot improve the result

There is no universal “winning” letter. A clear timeline and relevant evidence matter more than a particular phrase.

A few limits are easy to miss:

• The FTC sample letter is a format, not an automatic refund request.
• The 60-day credit-card billing-error deadline does not apply to every debit, prepaid, bank-transfer, or payment-app dispute.
• Card-network labels and reason codes are not the same as consumer-law rights. Describe the facts instead of guessing a code.
• Contacting the merchant can create useful evidence, but a merchant conversation should not make you miss the issuer's deadline.
• A merchant's refusal does not decide how the issuer must review a claim.
• If you open a payment-app case and a card dispute for the same transaction, tell both providers about the other case. Don't accept duplicate recoveries.

If the issuer denies the dispute

Start with the written denial. It may say the notice was late, went to the wrong address, lacked supporting records, or did not fit the type of transaction described.

Then:

1. Ask for the written reason and the deadline for reconsideration or appeal.
2. Ask what information the issuer relied on and whether its process allows you to request copies or a description of that information.
3. Send new or clearer evidence rather than repeating the same bundle.
4. Point out the specific error in the decision with a short chronology.
5. Continue paying undisputed amounts while any review continues.
6. If the issuer failed to address a timely credit-card billing-error notice or did not follow its stated process, use the issuer's complaint channel and consider filing a complaint with the Consumer Financial Protection Bureau.

A regulator complaint may prompt a response, but it doesn't guarantee that the charge will be reversed. A substantial loss or complicated contract dispute may call for advice from a qualified consumer professional in your state.

Common questions

Can I use this letter for a debit-card dispute?

You can use the same factual structure, but don't assume the credit-card rules apply. Debit-card disputes may involve electronic-transfer protections, card-network rules, and the bank's account agreement. Report unauthorized activity promptly and ask whether the bank requires a phone report, online form, written notice, or supporting affidavit.

What if I missed the 60-day credit-card deadline?

Send the dispute anyway and explain the delay. The federal billing-error procedure may not apply after the deadline, but the issuer, card network, or merchant may offer another review process. The claim isn't automatically accepted, and it isn't necessarily impossible.

Can I dispute a charge after the merchant says no?

You can still ask the issuer about the applicable dispute process. Include the date you contacted the seller, the seller's response, and the records supporting your position. A “no refund” response doesn't replace the issuer's review.

How long does a credit-card dispute take?

For a timely written billing-error notice, the issuer generally must acknowledge it within 30 days unless it resolves the issue sooner. It generally must resolve the dispute within two complete billing cycles and no later than 90 days. Debit-card, payment-app, and card-network procedures can use different timelines.

Open the statement before writing: mark the posted charge, note when the statement was sent, identify the payment method, and assemble the records that support your version of events. Then send the dispute to the correct issuer or provider before its deadline.
