My gamertag is: KC FG17. I preordered and have been playing Halo 4 since launch, yet I did not recieve any email with the codes for the other specializations. I am aware that you were to have been playing before Nov. 20th,(hence the reason I mentioned playing since launch) and I did check my spam folder and go through all the other preliminary measures. I was instructed by Xbox live support to post in this forum concerning the issue. Please instruct further.. thank you
