Specializations code not received

Hi,

As of today, I heard from a friend that he received his code to unlock the six other specializations of halo 4. I didn’t pay attention until now, but I noticed that I didn’t receive anything (by xbox live center message or email)until now. I searched a bit with google and found out a topic of this forum, where it was possible to send the gamertag and answers to some required questions to receive a code. But the topic seems to be closed (four days ago when i last checked).

The email attached to my gamertag is valid and I checked in the spam section, I got nothing. I played a bit almost everyday since the launch of Halo 4 and I didn’t see any xbox live message containing a code either.

Now I’m wondering if its still possible to receive a code to unlock those new specializations.

here’s the informations needed :
Gamertag : Saviorsixxx
Confirmation (by saying yes or no) you played the game while connected to Xbox LIVE before 11:59:59 P.M. Eastern Time on November 20, 2012 : yes
Confirmation (by saying yes or no) you are 17 years of age and older : yes, I’m 21
Confirmation (by saying yes or no) you live in the United States, Canada, Chile, Mexico, Colombia, Brazil, Japan, Hong Kong, Singapore, Korea, Taiwan, Australia, New Zealand, or India : yes, Canada

Hope there is something to be done !

Edit : Received the code by LIVE message yesterday and works just fine. Problem solved !
