Halo 4 Spec Code issue

Dear 343,

I received my Halo 4 Specialization unlock code via email and when I logged into my account and applied the code I found that I had logged into an old account that was I opened while I was waiting for this one to get returned to me after being hacked.

The code was applied to gamertag LuminousShrimp0 instead of my current gamertag, Frigidmonkey. I receive email for both at the same e-mail. Is there a way to get the content transferred to the proper gamertag or to have the first code invalidated and another sent?

Thank you for any help in advance.
