I try'd to sign on and said banned until 12/31/9999 and i have received an email that said for marketplace theft. Not only have i not purchased anything from marketplace other than a gamertag change on August the 29th but i have spent a numerous amount on microsoft points and live cards in the past few years to where this shouldn't happen. I want proof that i have committed marketplace theft and how this has happened? I have too much money in this account to just let it go and make a new one. My gt is KamikazePoptart i have proof that this is my gt and even some of the cards i have purchased in the past. So please contact me. If you guys are unable to fix this problem please remove my credit card from the account.
