Save the first statement showing the error and promptly contact the issuer. For the federal billing-error procedure, ensure written notice reaches the designated address on time, pay undisputed amounts, and distinguish provisional adjustments from the final decision. A merchant conversation alone does not preserve every cardholder right.

A duplicate charge is easy to spot and surprisingly easy to mishandle. You might spend several weeks waiting for a merchant refund while the issuer’s separate billing-dispute clock continues to run. Start both your factual review and the issuer notification promptly.
This guide concerns U.S. consumer credit cards. A debit-card withdrawal or dissatisfaction with the quality of an accepted product may involve a different procedure.
Identify what actually posted
Compare the statement with receipts, order confirmations, and activity by authorized users. Record transaction and posting dates separately. A pending authorization is not necessarily a second completed charge; an unfamiliar billing name is not proof of fraud. Report concerns promptly while asking for clarification.
The FTC’s credit-card guidance describes common billing problems. State exactly what you dispute: a duplicate entry, an incorrect amount, a missing payment credit, or goods not delivered as agreed. Avoid describing every merchant disagreement as unauthorized use.
Preserve the written-notice deadline
Under Regulation Z § 1026.13, a qualifying billing-error notice must reach the disclosed address within 60 days after the issuer sends the first statement reflecting the error. Do not restart that clock from your latest merchant conversation. Missing credits have their own statement-based application of the rule.
Read the billing-rights disclosure and find the dispute address, which may differ from the payment address. Send early enough for receipt and retain the notice and delivery evidence. An electronic submission can satisfy the written requirement when the issuer says it accepts notices electronically and specifies the method; an ordinary chat box is not automatically that method.
CFPB’s consumer explanation recommends prompt issuer contact and written follow-up. Already paying the charge does not, by itself, prevent a dispute.
Build a small, readable evidence file
For a hypothetical $85 purchase charged twice, identify one $85 entry as the disputed duplicate. Disputing $170 would misstate the correction you need. Include the relevant statement page, receipt, order reference, and a short explanation linking the documents.
A useful notice identifies the account securely, the statement date, the transaction, the amount believed wrong, and why. Keep originals and submit copies. Maintain a separate log of the case number, submission dates, requested documents, and your responses. Do not publish card numbers or unredacted statements in a review or public support forum.
Keep correct payments moving
The applicable procedure protects the disputed portion while it is investigated, but you remain responsible for correct charges. Do not stop paying an entire statement because one item is disputed.
Check automatic payments separately. The regulation has specific timing provisions for automatic plans offered by the card issuer; an external bank’s bill-pay instruction is a different arrangement. Confirm the next scheduled debit and how the issuer is treating the dispute. A case number does not establish that every payment instruction has changed.
Reconcile the result instead of watching one balance
The issuer generally has 30 days to acknowledge a qualifying notice, unless it completes the required resolution first. Resolution must occur within two complete billing cycles and no later than 90 days after receipt. These are procedural limits, not a promise that your position will prevail.
Label each adjustment as provisional or final. If the merchant separately refunds the same $85, tell the issuer and reconcile any offset so you do not count two permanent refunds. Read an adverse determination for its explanation, amount due, and payment date, then identify the particular evidence you believe was missed.
Keep the final decision with the next statement showing the correction. For a broader identity problem, use the identity-theft recovery guide. For delivery problems, preserve the timeline in the online-order delay guide.

Frequently asked questions
Does a phone call replace written notice?
Do not assume so. Follow the billing-rights disclosure; an electronic notice can satisfy the requirement when the issuer expressly accepts it through the stated method.
Can I stop paying the entire bill?
Continue paying correct, undisputed charges on time. Confirm how automatic payments handle the disputed portion under the applicable procedure.
Does a temporary credit mean the dispute is final?
No. Read the final determination and later statements, and reconcile temporary credits, merchant refunds, and permanent corrections.
