I got an email that a customer used a stolen credit card. Not only was I forced to refund the money (not even taking into account the fees I paid), I also had to pay an extra $25 as punishment for someone else's crime! It is not my fault that a customer used a stolen credit, just like if I owned a physical shop and someone paid with stolen cash, that is not my problem. My job is just to accept the payment and ship the goods. I am now looking for another provider.
