Halo 4 content issue

First things first, I apologize if this is in the wrong place! (Wasn’t sure if I should post here, or somewhere else) But I was hoping to find some help on this issue. So, I pre-ordered Halo 4, got it at midnight along with my bonus content codes put the codes in on my friends extra Xbox (Wasn’t at home, was in a different city, didn’t have MY Xbox). Everything was dandy. I had my BR skin, emblems and whatnot all unlocked.(Thought nothing of it at the time. Thought it would all stick since all of the content was online) When I got home, I got online and had none of that. Tried one of the codes again on MY Xbox, of course it had already been used. I tried deleting and re-downloading my XBL account to see if that would fix it, sadly, it did not. Now, every time that I rank up in game, all of that bonus content I should have pops up saying that I unlocked it. Every time I go to check, it’s all still missing. Since it’s a hand full of bonus items, it takes up the whole list every time I rank up I never get to see what I actually unlocked. I was hoping I could get in contact with someone that could maybe give me new codes for the items? If not, at least clear it off of there as if i never redeemed those codes? I can live without the bonus content, it has just become annoying seeing that every single time.(Tried the Xbox forums as well. Didn’t get a solution there. :\ ) Thank you for your time!
