I have to agree with DiapDealer, although agreeing with someone with a name like that kind of rankles.
I live in a rural area and don't have a car so I buy nearly everything from Amazon. Typically 8 to 10 purchases a month; often more. I bought the computer I'm typing on now from Amazon.
I got a couple of defective Acer's before I got this Asus. Both times I was offered a full refund on my credit card. With the second one I took it and the money was on my card much sooner than Amazon promised.
I try to avoid returning things unless they're defective or they sent me the wrong thing. Both have happened although not often. In every situation they were eager to make it right and how they did it was usually left up to me.
I wonder if you just happened into some Christmas help and lost your cool and got them mad. In any case your situation is far from the ordinary one with Amazon. I suggest giving them a call and calmly explaining your situation and how you feel about it. Be polite and see what happens. I'll be surprised if you don't get some satisfaction.
