Halo 4 SR70 Stuck??

Hello, I’ve been playing halo4 for a little while i DID NOT pre order. I did not buy the limited edition. i did not get a promo code to get my other specs. I did get a message in my xbox inbox saying " Xbox Live message center" I called micrsoft and they could not help me they gave me a Number to some kind of studios and it was a false Number. If any admin or mod that can help me it would be much appreciated.

I have a buddy that lives down the street he has been SR-70 for over 2 weeks. i do not think its fair that you have to pre order or buy limited edition to get to the max rank and get other specs. Ive only gotten Wetwork and Operator.

I did clear the cache on my console system. i redownloaded my profile to make sure that the code was sent and there was nothing. im not sure what else to do so if anyone can help me out it would be much appreciated
