Keep in mind that Amazon is not just going to call the card company, they’re going to build your case and present it on your behalf to the bank in question. For this service, Amazon will charge 20 USD per chargeback. However, if it’s determined that the event is covered by the Payment Protection Policy, you will not be charged for the 20 USD fee nor the chargeback claim. The same is true for the opposite scenario where if you are not covered by the Payment Protection Policy both charges will be debited to your account. Before disputing any Amazon Chargeback, review everything and make sure you have a solid case; or it could cost you a bit extra.
