I personally called Xbox live support to find they had actually messed up on my email. It was under a name I don't know so I had them change it to my actual email. What I don't understand is how did that happen to began with and how was I able to recover my account with the email they change it to today prior to the change? I know those two things I mentioned above are not related to 343 industries but I have had the game pre ordered and have been playing online since launch. Now that's been said how does one benefit off the "free gift" others have been benefiting off of that payed the same as I.

I called Xbox support to find they messed up and had my primary email wrong. It is fixed now and I have had and played halo 4 since launch day. Who do I need to talk to on fixing this or what do I need to do?
