A chargeback is a dispute filed by a customer with their credit card company or bank. Chargebacks can be filed for reasons like an unauthorized charge, fraud, or a customer not recognizing a charge. The process and sites for handling chargebacks depends on the credit card brand - American Express charges go to Amex while Visa, Mastercard, and Discover charges go to Litle. When a chargeback is received, the company can choose to contest the charge by providing proof the charge was valid, or accept the chargeback by refunding the customer and cancelling future charges. The documentation outlines the company's current process for handling chargebacks and communicating their status.
