Specializations Priority Alpha

when this code for Halo 4s specializations was sent to my email i was signed into the wrong Microsoft account, and the code got redeemed to an account that has never even been used before. so now im stuck at level 70 with no specializations to use besides operator and wetworks. xbox live support was no help and said they cannot issue out any codes.

somebody HELP!!! i bought this game to get all the specializations not get stopped at level 70. without that code this game has seemed to lose all its purpose. and i really dont want to have to spend 60 additional dollars to give that account xbox live and have to start all the way over from the beginning of halo 4.

please somebody help me find a way to get another specializations code.
