Start with the payment method, then describe one transaction and one specific problem. A useful credit-card example is: "I returned the goods on [date], but the promised credit has not appeared." Don't use an unauthorized-fraud example for a subscription charge that was authorized at first but continued after cancellation.

A chargeback is a review, not an automatic refund. The issuer may ask the merchant for records before deciding whether to reverse the transaction. A merchant's refund policy, card-network rules, bank workflow, and PayPal's dispute system can overlap, but they aren't interchangeable.

U.S. scope: The 60-day, 30-day, and 90-day milestones below describe the federal credit-card billing-error process. Debit cards, prepaid cards, bank transfers, and PayPal-native payments can follow different rules and deadlines. This is general consumer information, not legal advice.

The examples here are fact patterns and wording models, not guaranteed wins. Banks generally don't publish enough case detail to verify individual "success stories."

Pick the dispute route first

The payment rail usually matters more than the merchant's industry or the amount involved.

For a qualifying U.S. credit-card billing error, the Federal Trade Commission's guidance says the issuer must receive written notice within 60 days after the first bill containing the error was sent. The issuer generally must acknowledge the complaint in writing within 30 days, unless it has already resolved the matter, and resolve it within 90 days.

The text of Regulation Z covers specific categories, including a transaction the consumer did not make or authorize, an amount that was misstated, a charge that was not properly identified, a payment or credit that was not applied correctly, certain accounting errors, and goods or services that were not delivered as agreed.

A phone call or in-app report may open the issuer's internal case, but don't rely on a call alone if you want to use the federal written-notice procedure. Follow the issuer's billing-dispute instructions and keep a copy of anything submitted.

If you moved, the FTC also says the issuer must have received your written change of address at least 20 days before the billing period ended for this procedure. If that may apply, check the issuer's instructions instead of assuming the old statement address is enough.

Chargeback dispute examples

Keep the explanation narrow. Evidence that proves a delivery failure may not prove an unauthorized transaction.

None of these descriptions guarantees a reversal. An authorized subscription should not be reported as unauthorized just because the consumer later tried to cancel it. Explain the cancellation, disclosure, or recurring-charge problem instead.

A "no refunds" policy may affect a voluntary merchant refund, but it doesn't by itself decide whether an issuer will review a claimed unauthorized or incorrect charge. The issuer will assess the facts, documents, and applicable rules.

How to dispute a credit-card charge

1. Confirm the charge and the payment method

Read the statement before writing the dispute. Check:

• The statement and posting dates
• The amount
• The merchant descriptor
• Whether another household member or authorized user made the purchase
• Whether the payment went directly to the merchant or through PayPal or another service

A statement descriptor may not match the store or app name. If the transaction appears genuinely unauthorized, contact the issuer promptly using the number on the card or in the official banking app. Follow its instructions for securing the card and account.

2. Contact the merchant when it makes sense

A merchant can sometimes fix a delivery, return, duplicate-charge, or missing-refund problem faster than a formal dispute can. Ask for a specific remedy and create a record. Include the order or transaction number, what went wrong, the date of your request, and the date by which you want a response.

Save the reply, case number, and any promised resolution date. Don't wait for the seller if the 60-day credit-card deadline is approaching. Send the issuer's written notice first and mention the merchant contact in the letter.

For an unauthorized transaction, contact the issuer first if the account may still be at risk.

3. Put the evidence in date order

A short timeline is easier to review than a folder of unrelated screenshots. Note:

1. When the charge posted
2. What the seller promised
3. When the delivery, return, cancellation, or other event occurred
4. When you contacted the seller
5. What the seller or issuer said in response

Attach relevant copies, such as:

• The statement page with the charge marked
• The receipt, invoice, or order confirmation
• The advertised terms or cancellation policy
• Delivery, return, or pickup records
• Emails, chat messages, and support ticket numbers
• Screenshots of the product description or cancellation attempt
• The date and result of each call or message

Send copies, not originals. The FTC's sample dispute letter also advises consumers to keep the originals.

4. Send a precise written notice

Use the billing-inquiries address or submission method identified by the issuer. It may not be the same address used for card payments.

Identify the account, transaction date, merchant, amount, and exact reason for the dispute. Say what correction you want and list the documents attached. If the issuer accepts secure online uploads, save the submitted file and confirmation number.

The letter doesn't need a long accusation. A dated account of what happened is more useful than saying only that the merchant "scammed" you.

5. Track the issuer's response

For a qualifying federal credit-card billing error, mark the issuer's receipt date on your calendar. The issuer generally must acknowledge the complaint within 30 days, unless it has already resolved it, and resolve the dispute within 90 days.

Watch later statements, account messages, and requests for more information. Pay any amount that isn't part of the dispute, and ask the issuer how it wants the disputed amount handled while the investigation is open. Treat a temporary credit as provisional unless the issuer confirms that it is final.

If the issuer asks for more information, respond by the stated deadline. Keep the submission, delivery confirmation, and case numbers together.

Re: Billing error on credit-card account [account number or last four digits]

Dear Billing Inquiries Team:

I am writing to dispute a charge of $[amount] posted on [date] from [merchant name]. I believe this is a billing error because [choose and explain the accurate reason: I did not make or authorize the transaction; the goods were not delivered; I returned the goods and the promised credit is missing; I was charged the wrong amount; I was charged twice; or another specific billing problem occurred].

The relevant facts are:
[Give a short timeline with dates.]
[State any contact with the merchant and the response.]
[State the correction you want.]

Please investigate this charge and correct my account. Enclosed are copies of [list the documents]. Please send written confirmation of the result.

Sincerely,

[Your name]
[Mailing address]
[Phone or email]

The FTC's sample wording uses concise descriptions such as "the items weren't delivered," "I was overcharged," "I returned the items," and "I did not buy the items." Use the description that is true for this transaction.

For a debit-card transaction, don't assume that labeling the letter a federal credit-card billing error gives you the same protections. Use the bank's debit-dispute instructions and describe the actual payment method.

Short message to the merchant

A written request can help with a missing refund, delivery problem, or duplicate charge.

Subject: Request to correct transaction [order or transaction number]

On [date], I paid [amount] for [product or service] using [payment method]. The problem is [item was not delivered, item was returned, charge was duplicated, or another precise issue].

I am requesting [refund, replacement, delivery confirmation, or correction]. Please confirm the resolution in writing. I have attached [receipt, tracking record, cancellation confirmation, or other evidence].

Please reply by [date]. I am keeping a copy of this request and the supporting records.

Don't include your full card number in ordinary email or messages. Use the merchant's secure support channel.

PayPal and bank-specific dispute examples

PayPal payments

PayPal's published customer dispute and claim process is separate from the federal credit-card billing-error procedure.

For a PayPal-native payment, the process generally starts with a dispute in the Resolution Center after the buyer tries to resolve the issue with the seller. PayPal describes about 20 days before an unresolved dispute can be escalated to a claim. Once a claim is filed, the seller is generally given 10 days to respond, and PayPal says resolution usually takes about 30 days, although complex cases can take longer.

Those are PayPal process milestones, not a universal deadline for every PayPal-funded transaction. Check the case screen and the current PayPal terms for the transaction.

If a credit card funded the PayPal payment, ask the card issuer how its process interacts with the open PayPal case. Tell both providers about another pending case, and don't accept or pursue two recoveries for the same charge.

Chase and other card issuers

Chase says cardholders can begin a credit-card dispute through its dispute instructions. Its credit-card dispute guidance also says the transaction is reversed if the bank agrees with the dispute.

That page is useful for starting Chase's workflow, but it isn't a universal schedule for every issuer. Don't rely on a claim such as "the bank takes 30 to 60 days." Follow the deadline and document request shown in your account or in the issuer's current instructions.

The consumer's 60-day written-notice period is not automatically a merchant-response deadline. A merchant receives its instructions from the acquiring bank or card-network process.

Mistakes that can weaken a dispute

• Waiting until the deadline is close while negotiating with the seller
• Relying only on a phone report when written notice is needed for the federal procedure
• Calling an authorized subscription "fraud" instead of explaining the cancellation or disclosure problem
• Sending a large pile of screenshots without marking the relevant transaction and dates
• Sending original receipts or documents
• Disputing the wrong amount or merchant descriptor
• Ignoring a request for more information
• Treating a provisional credit as a final decision
• Opening a PayPal case without checking whether the card issuer has a separate process
• Seeking both a merchant refund and a chargeback without telling the providers about the other action

If the issuer denies the dispute

A denial usually tells you which part of the record the issuer found unpersuasive. Read it before sending another explanation.

1. Identify the stated reason. It may involve timing, authorization, delivery, refund status, or insufficient evidence.
2. Request the records used in the decision. Ask for the merchant's response and other supporting documents the issuer can provide.
3. Compare the decision with your timeline. Look for a missed date, a credit posted under another descriptor, or evidence that doesn't address the actual problem.
4. Send a focused appeal or reconsideration request. Match each disputed point with a dated document. Don't turn an authorized purchase into an unauthorized-fraud claim because the first explanation failed.
5. Use the issuer's formal complaint or appeal route. Keep the original notice, denial, supporting records, and follow-up together.
6. Consider a separate contract or consumer complaint route if appropriate. A chargeback decision doesn't resolve every warranty, contract, or state-law issue.

If the issuer missed a required acknowledgment or resolution milestone, list the relevant receipt and response dates in your follow-up and ask for an explanation. A missed date does not automatically guarantee a refund.

Frequently asked questions

Does the 60-day deadline run from the purchase date?

For the federal credit-card billing-error procedure, the FTC says the written notice must reach the issuer within 60 days after the first statement containing the error was sent. That is not the same as 60 days after the purchase. Other payment methods and voluntary issuer programs may use different clocks.

Do I have to contact the merchant first?

Contacting the merchant may resolve the issue faster and creates useful evidence, but don't wait if the credit-card notice deadline is approaching. For an unauthorized transaction, contact the issuer promptly and follow its security instructions.

Can I dispute a charge I authorized?

You can report an authorized transaction if the amount is wrong, the goods were not delivered, a promised refund is missing, or another specific billing problem occurred. Describe that problem accurately. Regret, poor customer service, or a later change of mind doesn't turn an authorized purchase into an unauthorized one.

Is a PayPal dispute the same as a credit-card chargeback?

No. PayPal uses its Resolution Center, while a credit-card issuer uses its own dispute and billing-error procedures. The route depends on how the payment was funded and which provider is handling the claim.

What evidence helps with an item-not-received dispute?

Start with the order confirmation, promised delivery date, tracking information, seller communications, and any refund request. Explain what the tracking actually shows rather than simply calling the seller dishonest.

What should I do after a denial?

Ask for the written reason, the evidence considered, and the next appeal deadline. Submit a short, dated response to that specific reason, then continue watching later statements and issuer messages.
