Chargeback period: "Typically 120 days"
What Is a Chargeback?
A chargeback is a charge that is returned to a payment card after a customer successfully disputes an item on their account statement or transactions report. A chargeback may occur on debit cards (and the underlying bank account) or on credit cards. Chargebacks can be granted to a cardholder for a variety of reasons.
In the U.S. chargeback reversals for debit cards are governed by Regulation E of the Electronic Fund Transfer Act. Chargeback reversal for credit cards are governed by Regulation Z of the Truth in Lending Act.
