I have recently talked to a xbox support chat lady and she said to post here about the problem i am having.
i have gathered all the requirements for the halo 4 armour unlock( the one to keep levelling up) and i dont think i have recieved it as of yet. I am over 17, live in australia have played before the cut off date. Also i have checked both email accounts (junk and delted) i dont think i have recieved it.
hopefully someone helps,
