>>all I had to do was find the item in my order history click a button, answer a few questions and in this case they just credited the amount to my account

Exactly the same as with Amazon here in the UK then. They have every retailer in this country absolutely beat on their approach to customer support - it's always no faff, easy, often instant refund, none of this waiting 60 minutes on the phone to speak with unhelpful CS for any of the major retailers. John Lewis were the only ones approaching Amazon in the quality of their customer service, but recently that has changed for much worse and they are as hostile as everyone else.
