A duplicate charge is frustrating. A card issuer that ignores a properly submitted dispute raises a different question: has it broken federal billing-error rules? A possible claim depends on the error, the notice and the issuer’s response—not simply on whether a merchant refuses a refund.
This article provides general information about US consumer credit cards, checked on 16 October 2026. It is not legal advice. Debit cards, business accounts and UK cards have different rules; state law and individual facts may also affect a dispute.
What counts as a billing error?
Regulation Z, section 1026.13(a), covers categories including unauthorised charges, accounting mistakes, payments or credits not properly recorded, and goods or services not accepted or not delivered as agreed. A complaint about the quality of something already accepted is outside that last category. Acceptance can depend on state law.
For example, an order that never arrived and an accepted appliance that later disappoints are not automatically the same kind of dispute. The CFPB notes that defective goods may involve a different dispute process. A merchant refund request also differs from a complaint about the card issuer’s own conduct.
The notice deadline matters
Under section 1026.13(b), the creditor generally must receive written notice at its designated billing-inquiries address within 60 days after it transmitted the first statement showing the alleged error. This is a receipt deadline, not simply a mailing deadline. Electronic notice qualifies when submitted through the method the creditor specifies in its billing-rights statement.
The CFPB’s practical guide explains that the billing-dispute address can differ from the payment address. A notice should identify the account and explain the disputed amount and why it appears wrong. Copies of the statement, notice and delivery evidence help establish what happened. A telephone conversation alone should not be assumed to preserve the written-notice protections.
How long does the issuer have?
The FDIC’s credit-card guidance describes two separate time limits after receipt of a qualifying notice: acknowledgment within 30 days unless the matter is already resolved, and resolution within two complete billing cycles, never more than 90 days. Those periods run from receipt; they are not consecutive extensions.
The CFPB explains that paying a charge does not itself prevent a dispute. If the issuer rejects the dispute, it must explain its conclusion in writing and state the amount owed and when payment is due. A rejection alone does not establish that the issuer violated the law.
Does a dispute mean the whole bill can go unpaid?
No. For a qualifying billing-error dispute, the CFPB distinguishes the disputed amount and related charges from the rest of the bill. Correct, undisputed charges remain payable on time. The existence of a complaint is not a blanket payment holiday. Uncertainty about which amounts qualify needs individual assessment before changing payments.
When might a lawsuit be possible?
15 USC section 1640 provides civil liability for covered violations of the Truth in Lending Act, including its billing-error provisions. Depending on the violation and applicable requirements, remedies may include actual damages, statutory damages and costs and reasonable attorney’s fees in a successful action. Compensation is not automatic, and statutory defences can matter.
Section 1640(e) generally sets a one-year deadline from the occurrence of the violation for a claim of this kind. Identifying that date and any exceptions requires case-specific analysis. The 60-day notice window and a court filing deadline serve different purposes.
A consumer-law attorney or legal-aid service can assess notice compliance, the issuer’s response, available remedies and the appropriate forum. Useful records include the first affected statement, receipts, correspondence and proof of receipt. None of those records alone guarantees a viable claim.
