Mate I'm glad you bent them back and I hope it works.
I just want to say that it is an outrage that the store wont take it back, in the uk there are trading standards to adhere and by not replacing it they would be braking the law they seem to be assuming you are guilty until proven innocent and, as we all know, it is the other way around.
If a company did this to me in the UK i would take it higher, maybe head office or trading standards (or whoever regulates trade where you are), I mean its not like frys would be out of pocket they would just return it to amd and prob get a replacement or a refund.
Idk how old you are but if you are still quite young it may have helped to bring your parents along, older generations always seem to get better results, I think businesses just trust them more.
Anyway good luck.
