specialazations codes

It has been 3 days for me not to be able to rank up. I either did not recieve the specialazations codes or deleted them by mistake. All I know is I am not happy about this at all. And no one has been able to help me. Don’t even feel like playing whats the sense since I cant rank up.

I recieved a specialization code today via xbox live message center and the code is invalid!!! i called support and was told to come to the halo forums and post on a thread explaining my issue and that someone would issue me a new code. my gamertag is Mayniac and yes i meet all requirmeents for the specialization early access code. thanks!
