I'm trying to recover an old Live account that I had about 3 years ago. My previous Xbox RRoD'ed and it wasn't until about May of this year that I purchased a new one. I have a new account now but I'd like to recover my old account as well(it had a lot of Rock Band DLC) Problem is: I don't remember what I used for a Live ID. I can guess the password because I've used the same 5 passwords for everything else.
I've already tried calling customer support and according to them, the only way to get any info is if I remember the last 4 digits of a credit card attached to the account that has long since been cancelled and replaced. I have no clue what the four digits were. Is there any other possible way to get my account back?
