If a U.S. credit card charge is unauthorized, wrong, duplicated, or tied to goods or services that were not delivered as agreed, contact the card issuer promptly. For the federal billing-error procedure, the issuer generally must receive your written notice within 60 days after it sent the first statement showing the error.
That 60-day deadline is easy to miss. It also isn't a universal chargeback deadline: card-network workflows and a bank's separate dispute process may use different dates. Report the problem now, send written notice to the correct address, and keep every record.
The rule that controls your dispute
"Chargeback" is the everyday term for asking a card issuer to reverse a transaction. It isn't a guaranteed refund, and it isn't the same thing as a lawsuit. The issuer reviews the claim, may seek information from the merchant, and decides which process applies.
The CFPB billing-error regulation and the matching eCFR text for Regulation Z control the federal process for many U.S. credit card billing errors.
| Your situation | Main rule or process | What to do first |
|---|---|---|
| A U.S. credit card billing error | The Fair Credit Billing Act, implemented through Regulation Z | Send a written billing-error notice within the federal deadline |
| A card-network dispute | Your issuer's procedures and network operating rules | Follow the issuer's instructions and its stated submission date |
| A debit or prepaid card problem | Different payment rules and bank procedures | Report it promptly and ask which dispute process applies |
| A complaint about the bank | A regulator complaint route | Keep your dispute records, then complain if the bank does not address the issue |
This article focuses on U.S. consumer credit cards. Rules for debit cards, bank transfers, and cards issued in other countries can differ.
What counts as a credit card billing error?
Regulation Z covers more than stolen card numbers. Examples include a transaction you did not make or authorize, a statement entry that is not properly identified, a payment or credit that was not posted correctly, and certain accounting errors.
The rule also covers goods or services you did not accept or that were not delivered as agreed. The facts matter.
| Billing problem | Useful description |
|---|---|
| Unauthorized charge | You did not make the transaction, and the person who used the account did not have authority |
| Statement entry problem | The transaction is missing information or does not match the account records |
| Payment or credit problem | A payment, refund, or other credit was not posted correctly |
| Accounting problem | The amount reflects a calculation or similar accounting error |
| Delivery or acceptance problem | Goods or services were not accepted or were not delivered as agreed |
A product that simply disappointed you is not automatically a federal billing error. It may still fit an issuer or network dispute category, so describe the actual problem rather than choosing the strongest-sounding label.
How to file a credit card chargeback dispute
-
Contact the issuer quickly. Use the phone number on the card or the issuer's secure app. If fraud is involved, ask whether the card should be blocked or replaced, and record when you reported it.
-
Find the first statement showing the charge. The federal deadline generally runs from when the issuer sent that statement, not from the day you noticed the transaction. Save a copy of the statement.
-
Contact the merchant if practical. Ask for a refund or correction in writing. That may solve a straightforward problem faster, but it should not delay your billing-error notice.
-
Send written notice to the right address. Use the address listed for billing-error inquiries, which may differ from the address used for payments. A phone call alone is not the safest way to preserve the federal written-notice procedure.
-
Explain the transaction clearly. Include your name, account details, transaction date, amount, and the reason you believe the charge is wrong. Attach copies, not originals, of supporting records.
-
Pay the undisputed part of the bill. Do not assume that a temporary credit means the matter is permanently resolved. Keep paying amounts outside the dispute and follow the issuer's instructions for the remaining balance.
-
Track the response. Save the letter, secure-message confirmation, delivery proof, case number, and every response. If the issuer denies the claim, ask for the reason in writing.
Turns out, a short and precise record often helps more than a large pile of unrelated screenshots.
Federal chargeback deadlines and investigation times
For a proper billing-error notice, Regulation Z generally sets these federal time limits:
| Event | General federal timing |
|---|---|
| Written notice reaches the issuer | No later than 60 days after the first statement showing the error was sent |
| Issuer acknowledges the notice | Within 30 days, unless the issuer has already resolved the issue |
| Issuer completes its investigation | Within two billing cycles, but no later than 90 days |
| Card-network or app submission | May have a separate issuer or network deadline |
The two-billing-cycle period is not always the same as two calendar months. Keep following messages from the issuer even if you receive provisional credit.
For a proper notice, the billing-error rules also limit how the creditor can handle the disputed amount while investigating. Pay the undisputed balance, and ask the issuer how it wants the disputed amount handled so the account does not become confusing or delinquent.
Evidence that makes a dispute easier to review
Match each document to a specific fact. A receipt may show that you paid, but it does not by itself show that an order was never delivered.
Useful records include:
- The statement page showing the date, amount, and merchant name
- The order confirmation, receipt, and advertised terms
- Emails, chats, and notes about contacting the merchant
- Cancellation, refund, or delivery records
- Tracking details, photos, or documents showing what happened
Don't send full card numbers unless the issuer specifically requests them through a secure channel. Redact unrelated personal information where practical.
A simple written notice can say: "I am disputing the $ charge from dated . I believe it is a billing error because . Please investigate under 12 CFR 1026.13. I have attached copies of the statement and supporting records."
What to do after a denial
An issuer's denial should tell you what it decided and why. Read that explanation closely. A claim may have been treated as a merchant-service complaint, a fraud report, or a formal Regulation Z billing-error notice, and those routes do not always use the same procedure.
Ask the issuer to identify the disputed transaction, the reason for the denial, and any evidence it relied on. Then answer the specific gap. If the merchant says an order was delivered, for example, respond with the delivery mismatch or the records showing a cancellation. Repeating the same general complaint usually adds little.
Thing is, an app message that says "case closed" may not explain whether the issuer reviewed the documents you sent. Ask for a written explanation and keep your request focused.
If the bank does not address the issue, you can submit a complaint through the CFPB complaint portal. The CFPB accepts credit card complaints, says companies generally respond within 15 days, and gives consumers 60 days to provide feedback on the response. A complaint is an escalation route, not an automatic refund.
For a national bank, federal savings association, or certain federal branches, the Office of the Comptroller of the Currency consumer complaint route may also be relevant.
Visa and Mastercard timelines are not one universal rule
Generic charts often list fixed Visa or Mastercard response periods. Those figures can depend on the dispute category, card product, issuer, acquirer, and stage of the network process.
The federal 60-day written-notice rule is separate. It applies to qualifying U.S. credit card billing errors under Regulation Z; it is not a promise made by Visa or Mastercard. Follow the deadline shown by your issuer, but do not wait past the federal notice deadline while trying to work out a network procedure.
| Question | Safer answer |
|---|---|
| Does Visa or Mastercard decide every consumer claim? | The issuer handles the consumer's account and uses the applicable network process |
| Is a 30-day or 45-day chart always accurate? | No. The applicable deadline can vary by reason and process stage |
| Does provisional credit mean you won? | No. It can be temporary while the issuer investigates |
| Is there a reliable universal win rate? | No. Regulation Z sets procedures, not a single consumer success percentage |
To be honest, a headline success statistic tells you little without the dispute reason, evidence, and review stage.
What merchants can do
The merchant normally receives the dispute through its acquiring bank or payment processor. It can answer with records such as the order details, delivery information, cancellation terms, refund history, and customer communications.
A merchant response is part of the review. It is not a court judgment, and the customer does not control the merchant's network deadline. If the issuer asks you for a response to the merchant's evidence, answer the exact point at issue.
Merchants should match evidence to the claim. A delivery record may address non-delivery, but it may not answer a cancellation or unauthorized-renewal complaint. Large data exports are less useful than a clear timeline.
Subscriptions, digital goods, and fraud
Recurring subscriptions
Save the signup confirmation, renewal terms, cancellation date, cancellation message, and the invoice for the disputed renewal. If you canceled before the charge, say exactly when and how you canceled.
A recurring charge does not become unauthorized merely because the customer no longer wants the subscription. The issuer will look at the authorization, cancellation history, and the merchant's terms.
Digital goods
Keep the product description, promised features, access records, download history, and support messages. Access to a digital product may be relevant, but it does not answer every complaint about quality, misrepresentation, or cancellation.
Unauthorized transactions
Report suspected fraud as soon as you see it. Give the issuer the facts you know, including whether the card was lost, whether you still have it, and whether you recognize the merchant.
Don't describe a purchase as unauthorized if you know that you or an authorized user made it. Ask the issuer which liability and network rules apply to your facts.
Credit card chargeback FAQs
Does calling the card issuer meet the 60-day deadline?
Do not rely on a call alone. For the federal billing-error procedure, send written notice that reaches the issuer within the deadline and use the billing-inquiry address provided by the issuer.
Must I contact the merchant before filing?
Contacting the merchant can help and may resolve the problem quickly. It should not cause you to miss the issuer's deadline, and the issuer may still ask what happened when you tried to resolve the issue.
Can I use this process for a debit card?
Not automatically. The Regulation Z process described here is for qualifying credit card billing errors. Debit, prepaid, and bank-transfer disputes can use different rules and deadlines, so contact the payment provider promptly.
What if the charge first appeared more than 60 days ago?
Report it immediately anyway. You may still have an issuer or network dispute route, but the federal written-notice protection may be harder to use after the deadline.
Does a chargeback guarantee a refund?
No. The issuer reviews the claim and the available evidence. A temporary credit, merchant response, or app status is not necessarily the final decision.
Your next step
Open the statement now and mark the first date showing the disputed charge. Then gather the transaction record, send written notice to the billing-error address, save proof that it arrived, and keep paying the undisputed part of the account on time.
