When I enter the code to redeem my prepaid card two error codes pop up. The first is 801613C9 and second is 80153021. I've read forums on them both and instructions on fixing the problem have not worked. I don't have a PC so I cannot chat with Xbox officials nor do I have a twitter so I believe this is my only option. I've re downloaded my profile countless times and checked my billing info twice as many. It says my account is locked and I cannot find out why or how to fix it. Any help would be greatly appreciated!
