SUMMARY:
In the case of an A-to-Z Guarantee claim, the buyer contacts Amazon to mediate a problem with their orders fulfilled by third-party sellers under the A-to-Z Guarantee program. With a Chargeback, the buyer contacts their bank or credit card company to dispute the charge for an order placed on Amazon. In this case, a bank or credit card company decides the outcome of a chargeback, not Amazon.
Chargeback Claims
Often referred to as a charge dispute, happens when a cardholder contacts their bank to challenge a charge related to an order made on Amazon. Various reasons can lead to a chargeback, spanning from not receiving the ordered product to unauthorized credit card usage.
