Never Received Message for Specializations

I never received an email or message for my unlock of the Specializations

My Gamertag is Cthuulhu
Yes I played the game while connected to Xbox LIVE before 11:59:59 P.M. Eastern Time on November 20, 2012
Yes I am 17 years of age and older (31)
Yes I live in the United States

What do I need to do to receive my message, I have read countless posts about people not receiving theirs, but not seen any solution. I have achievements dating back to the release date of the game, I can prove that I have played the game.
