Short answer: A merchant refund comes from the seller’s return, cancellation, or correction process. A credit card billing dispute uses a separate written process with the issuer to investigate an alleged billing error.

Start with the reason for the correction

If the seller agreed to a return, cancellation, or price correction, ask the seller for written confirmation and keep the receipt. Then review the card statement for the corresponding credit.

The FTC identifies an issuer’s failure to post a return credit as one type of billing error. A promised merchant refund and a dispute about an unposted credit can therefore become two stages of the same problem.

Understand a merchant refund

A merchant refund follows the seller’s process. Keep the seller’s refund confirmation, the original receipt, and the statement showing the purchase.

For example, a posted $120 purchase followed by a posted $120 refund has a net transaction effect of $0. A partial refund or separate charge would need its own calculation.

Understand an issuer dispute

A billing dispute asks the issuer to investigate an alleged error. The FTC lists examples including unauthorized charges, duplicate or incorrectly calculated charges, goods not delivered as agreed, and return credits the issuer did not post.

To use the federal billing-error process described by the FTC, send a written notice to the billing-inquiries address so it arrives within 60 days after the first bill containing the error was sent. Keep copies of the letter and supporting documents.

Keep the records connected

If a merchant credit posts after a dispute begins, keep that statement with the dispute records and notify the issuer through its official channel. The account record should reflect the later credit when the issuer evaluates the amount still disputed.

Keep a simple timeline of the purchase, seller contact, refund confirmation, written dispute, and statement entries. This shows whether the original amount, refund, and disputed amount refer to the same transaction.

Continue checking account instructions

While a billing-error dispute is investigated, the FTC says the cardholder may withhold the disputed amount and related finance charges but is still expected to pay the undisputed part of the bill.
