This really sucks but I think you did the right thing. You've already paid for the game so refusing it would just put it in the hands of the idiots that caused all the damage and you may never see it again. The problems you're having may or may not be related to the shipping damage and if it was me I would fix it up and get it playing 100%. I mean, why not? Selling it for a loss will just make things worse. At the same time keep working on getting reimbursed, at this point you have nothing to lose.
