Specialization Code Live Message

I just jumped back on xbox and found that I had a message saying I had not activated my Halo 4 specialization code and there was a code listed. I thought I had hit “B” but I might have accidently hit “X” and deleted the message before I could write the code down. What do I do? I remember this was suppose to be given out to those played Halo 4 before Nov 20th. Do I not get it now? Can I get one sent again? Maybe through my email so I can’t accidently delete it…

I did the same exact thing and am wondering the same exact thing… Ive already posted like this but no answers yet, if you find an answer please let me know
