What happened to all my armour! where is it?!?!?!?

A lot of my armour in the customise my Spartan section is either missing or gone.

I noticed I didn’t have the nightfall helmet, but I did have the two master chief like helmets. I was also missing all of the unlocks I should have got for my progress in the beta. I went and did the task (watch the second story of episode 1 of nightfall) to unlock the nightfall helmet and funny - the helmet doesn’t appear in customise my Spartan and the chief helmets are gone…

Is there someone I can contact or something I can do about this. I’m not too fussed if I will have all these unlocks in the full game when I customise my Spartan there but if I don’t that will really suck that I didn’t get the cool stuff I should have got. I’ve noticed a lot of people getting similar problems: missing Spartan customisation options. Anyone know of a fix, or comment from 343i on the issue?

I had a similar problem, earlier I had the Recruit, nightfall MK IV Gen 1 & MK IV Gen 1 - Scarred but I only have recruit now. Server bugs perhaps?
