my account has recently been banned until 12/31/9999. this does not bother me because i have multiple accounts that are 10th with everything on mw2 cod4 and waw with some rank on black ops and mw3 but what bothers me is that i have lost the gamertag. I need that gamertag. So is there a working way to change my gamertag on that account or even bypass the ban/unban it?
