Not receiving unlocked armor

Yeah i was supposed to unlock the recruit TIGR skin because i completed the extermination commendation all the way through master. I never saw it unlocked, only in its locked form. When i was supposed to get it, it disappeared entirely from my armory and i have no way to see or use it.

Can anybody help me fix this or at least tell me if i screwed something up somehow and now i cant ever use it?

thanks
