How do credit card chargebacks work?
<|assistant|>
A credit card chargeback is a reversal of a charge on the cardholder's account. It happens when the cardholder disputes a transaction that they didn't authorize or want reversed for another reason. The cardholder informs their bank of the dispute, which triggers an investigation of the transaction. If the bank finds in favor of the cardholder, they will return the money to the cardholder and send the money back to the merchant who processed the original transaction.
