I have a customer who is demanding a refund for a purchase made in August 2009. Usually my approach is to give refunds without a quibble, even if they are outside of my 30 day no questions asked guarantee period. I'd like to give this guy a refund too but my payment processor doesn't allow refunding CC charges past 90 days so my hands are tied.
What should I do?
Edited to add: I am in Australia, they are in the USA.
