The first mistake in a card dispute is treating every bad merchant experience as fraud. For a U.S. personal credit card, identify the transaction, then notify the issuer promptly. A merchant may issue a refund, but the issuer handles the card dispute.

For a qualifying credit-card billing error, the Federal Trade Commission's guidance says written notice must reach the issuer within 60 days after the first bill containing the error was sent to you. Send it to the address listed for billing disputes or billing inquiries, which may differ from the payment address. Keep a copy and proof of delivery.

The FTC also lists a written-change-of-address condition for using this process after a move: the issuer must have received the new address at least 20 days before the billing period ended. If an old address is part of the story, check the FTC instructions rather than assuming the deadline changed.

That 60-day process isn't a universal deadline for every payment. Debit cards, prepaid cards, ACH payments, peer-to-peer transfers, and wire transfers can follow different rules and provider procedures.

Refunds, chargebacks, and billing errors aren't the same

A merchant refund comes from the seller. It often returns money to the original payment method after a return, cancellation, or service adjustment. The original charge remains on the statement until the credit actually posts.

A chargeback starts when you report a card transaction to the issuer. The issuer or card network may reverse the payment while the merchant has a chance to respond. The merchant might submit receipts, delivery records, account activity, communications, or other evidence.

A billing error is a problem that fits the credit-card billing-error process. Not every disappointing purchase does. A strict no-refund policy may affect a voluntary refund, but it doesn't automatically decide whether a charge was unauthorized, duplicated, billed for the wrong amount, or made after a documented cancellation.

Check the transaction before calling it fraud

Compare the charge with your statement, receipts, email, account history, app subscriptions, and household purchases. A statement descriptor may show a legal business name, parent company, or payment processor instead of the storefront name.

If the charge is genuinely unauthorized, don't wait for a merchant response before notifying the issuer. A merchant may explain an unfamiliar descriptor, but it can't replace the issuer's fraud-reporting process.

Mistakes that can weaken a dispute

Waiting on a promised refund

A seller may say a refund is "processing." Save the promise, date, amount, and expected timing, then check whether the credit posts. If it doesn't, tell the issuer exactly what the merchant promised and when.

Don't let repeated customer-service conversations push you past the applicable dispute deadline.

Relying on a phone call alone

A phone call can open a customer-service case, but don't assume it satisfies the formal written-notice process for a credit-card billing error. Follow the instructions on your statement and send the notice in the required manner.

The FTC recommends keeping a copy of the dispute letter. Use the billing-dispute address, not automatically the address used for payments.

Choosing a more favorable dispute reason

Describe what happened and let the issuer apply the appropriate category. If you authorized the initial subscription but canceled before a later renewal, say that the disputed transaction was a recurring charge after cancellation. Calling the entire relationship "fraud" can create confusion if the merchant can document the earlier authorized purchase.

An item that arrived late is different from an item that never arrived. A duplicate charge is different from an unfamiliar descriptor. The timeline matters.

Treating a descriptor as proof of fraud

Check the amount, purchase date, receipts, app subscriptions, and household purchases. Ask the issuer whether it can identify the merchant more fully.

If you recognize the purchase after checking, use the merchant's return or refund process instead of making an inaccurate unauthorized-transaction claim. If you still don't recognize it, report it promptly through the issuer's fraud channel.

Sending an accusation instead of a timeline

"Merchant is lying" doesn't tell the issuer what needs to be investigated. A useful notice identifies:

• the transaction date, amount, and statement description;
• what happened and when you noticed the problem;
• whether you contacted the merchant;
• what the merchant said or promised;
• why the charge is incorrect; and
• which documents support your account.

Keep the tone factual. A short timeline is usually more useful than a long argument.

Providing no supporting records

A merchant may submit its own evidence. Provide the records that answer the likely response, such as:

• the order confirmation and receipt;
• screenshots of the advertised price or renewal terms;
• delivery tracking or proof of non-delivery;
• cancellation requests and confirmation numbers;
• emails, chat transcripts, or call notes;
• the statement showing the disputed amount; and
• a refund confirmation for a credit that hasn't posted.

A merchant's IP address, device record, or prior account activity may show that an account or device was used. Those records don't automatically prove that you authorized every disputed charge.

Stopping payment on the entire account

A dispute concerns a particular transaction or amount. Keep paying amounts you aren't disputing and follow the issuer's instructions during the investigation. Stopping payment on the whole balance can create separate problems.

If the issuer gives you a temporary credit, treat it as temporary until the case is formally closed.

Forgetting future recurring charges

Disputing one renewal doesn't necessarily cancel the subscription. Cancel with the merchant, save the confirmation, and ask the issuer what options are available if another charge appears.

The cancellation record remains useful even if the card is replaced.

Put a credit-card dispute in writing

For a personal U.S. credit card, use this sequence:

1. Write down the facts. Record the transaction date, amount, descriptor, and exact reason the charge is wrong.
2. Contact the merchant when appropriate. For an ordinary billing, delivery, or cancellation problem, ask for a correction or refund. Skip that delay if the charge is clearly unauthorized or the issuer tells you to report it immediately.
3. Notify the issuer. Use the billing-dispute address and meet the 60-day deadline when the claim is a qualifying credit-card billing error.
4. Attach focused evidence. Label documents by date and state what each one proves.
5. Keep submission records. Save the notice, online confirmation, delivery tracking, case number, and responses.
6. Answer follow-up requests. Respond by the issuer's deadline and correct any misunderstanding instead of submitting the same claim repeatedly.

Your notice can include:

• your name and the account details requested by the issuer;
• the transaction date, amount, and merchant descriptor;
• a plain description of the error;
• the date you contacted the merchant, if applicable;
• the correction you are requesting; and
• copies of relevant records.

Don't send a full card number through ordinary email. Use the issuer's secure channel or the instructions printed on your statement.

The FTC says the issuer generally must acknowledge a written complaint within 30 days unless it resolves the matter sooner, and resolve the dispute within 90 days. Follow the issuer's current instructions because the details can depend on the account and transaction.

When the merchant challenges the dispute

A merchant response isn't a reason to repeat the original complaint without addressing the new evidence. Read the response against your timeline.

• The merchant shows an initial subscription order: provide the later cancellation request and identify the renewal date.
• The merchant provides delivery confirmation: explain whether the address, item, date, or recipient is incorrect and attach relevant tracking or correspondence.
• The merchant says the descriptor was disclosed: clarify whether you now recognize the purchase. If you do, pursue the appropriate refund or service complaint instead.
• The merchant claims a refund was issued: provide the promised refund date and amount, along with the statement showing that the credit hasn't posted.
• The merchant submits account or device activity: explain why that activity doesn't resolve the specific issue, such as a later renewal or a different amount.

Don't make contradictory claims. If new information shows that the purchase was yours, tell the issuer and change the request to the problem that actually remains.

Keep a cancellation trail for subscriptions and free trials

Recurring billing disputes often turn on the sign-up terms, renewal timing, and cancellation history. Save the page or email showing:

• the price and billing frequency;
• the length of any free or discounted trial;
• when the first paid renewal would occur;
• how cancellation worked;
• the date and time you canceled; and
• the confirmation or ticket number.

The FTC's consumer alert about unwanted subscriptions addresses situations in which people report being enrolled in subscriptions or receiving products they didn't order.

The FTC's business guidance on recurring subscriptions describes negative-option programs as including automatic renewals and free trials. It also describes a material term as information that could affect a customer's decision to sign up. That guidance is useful context, but it isn't a case-specific refund decision. The actual terms, cancellation records, payment method, and issuer process still matter.

If you authorized the first payment but not a later renewal, say so clearly. If you never agreed to the subscription at all, preserve evidence showing how the charge appeared and report it as an unauthorized transaction.

Don't apply the credit-card deadline to every payment

The 60-day written-notice process discussed above is tied to qualifying credit-card billing errors.

A debit-card or bank-transfer dispute isn't automatically a credit-card chargeback. Calling it one won't create the protections or deadlines associated with another payment method.

If the issuer denies the dispute

Start by finding out why. The problem may be missing information, a deadline issue, evidence that doesn't address the stated error, or a conclusion that the transaction doesn't fit the issuer's billing-error process.

Then:

1. Request the explanation and ask what merchant evidence was considered.
2. Compare that evidence with your original timeline.
3. Send new, relevant documents by the issuer's stated deadline.
4. Use the issuer's appeal or reconsideration process if one is available.
5. Keep the original notice, responses, statements, and case numbers.

If you believe the issuer mishandled a written billing-error notice, ask about its formal complaint process and retain proof of each contact. For a large loss, identity-theft concern, or complicated subscription dispute, consider advice from a qualified consumer advocate or attorney.

FAQ

Is a chargeback the same as a refund?

No. A refund comes from the merchant. A chargeback begins with a dispute reported to the card issuer, which may reverse the transaction while the merchant responds.

Does the 60-day deadline start on the purchase date?

For the credit-card billing-error process described by the FTC, written notice should reach the issuer within 60 days after the first bill containing the error was sent. It isn't necessarily 60 days from the purchase date.

Can I use the same process for a debit-card charge?

Don't assume so. Debit, prepaid, ACH, and other payment methods can have different procedures and deadlines. Contact the bank or provider promptly and ask how to report the error.

What if the merchant has a no-refund policy?

A no-refund policy may affect a voluntary return or refund, but it doesn't automatically determine whether a charge was unauthorized or incorrectly billed. Explain the actual problem to the issuer and provide your records.

What should I do if I canceled a subscription but was charged again?

Keep the cancellation confirmation, contact the merchant for a refund, and notify the issuer if the charge remains incorrect. State the cancellation date and renewal date rather than describing the entire account as unauthorized unless that is accurate.
