Merchant Won’t Fix a Bad Credit-Card Purchase? Federal Law May Let You Assert the Same Claim Against the Card Issuer
Regulation Z preserves a consumer’s right in certain transactions to assert valid merchant claims or defenses against the credit-card issuer.
Who
Consumers with a qualifying credit-card purchase dispute where the merchant has been unwilling to resolve a valid claim or defense.
Where: United States
What to do
Start here: Document your attempt to resolve the issue with the merchant, then contact the card issuer in writing and identify the claim or defense and disputed transaction.
Eligibility: The general rule requires a good-faith attempt to resolve the dispute with the merchant, more than $50 of credit and a transaction in the same state as the cardholder’s address or within 100 miles, subject to statutory relationship exceptions.
What you get
After a good-faith attempt to resolve a qualifying purchase dispute with the merchant, a cardholder may be able to withhold the disputed outstanding credit and assert the underlying claim or defense against the issuer.
Benefit: Protection against having to pay the still-outstanding disputed credit amount when the federal conditions are met.
Possible value: Up to the amount of credit still outstanding for the disputed transaction, plus applicable finance or related charges under the rule.
Good to know
Important: This is not an automatic chargeback or refund. The rule preserves claims or defenses that are valid against the merchant; ordinary billing-error rights under Regulation Z are separate and may have different deadlines.
Availability: Active federal consumer-credit right
Why people miss it: Consumers usually know about chargebacks but not the separate federal claims-and-defenses rule that can apply when the merchant dispute itself remains unresolved.
