>Rule 2: Customer service is understanding<p>No, if you read this section, rule 2 should be that if you accept credit cards, you have a very liberal refund policy, like it or not.<p>You can choose to be an asshole about giving the money back, and make the customer go through the credit card dispute process, or you can be friendly and give the money back upon request. But the point is, you are going to be giving the money either way, so you might as well make it a less painful experience.
