I bought a 360 on ebay a few months ago and it had 8 months left on a Live Gold account. I spent the $10 or so to change the gamertag, but the account is still linked to the original owner's email address. I can't change the email, physical address, or anything else because I can't log onto his account online. The seller will not reply to my emails for assistance with this. If I call XBox is there any way they would help me, or am I out of luck without the password on the account?
