I have a gamertag that I have lost access to. the gamertag is still associated with my email account as I regularly receive announcements from Xbox live, but when I sign in a different gamertag comes up. I can't change the tag because I get the message "this gamertag is already in use" plus there is the 800 points that I also have to pay in order to change it. Just so its clear, I would have no problem paying the points, but its not worth it if I have to get a whole new gamertag, and lose all of those achievements. This is the second suc gamertag that I've lost access to. can somebody please help me?
