I'm assuming you're talking about Halo 4 so in that case. Xbox and 343 are working on getting the codes to the remaining people. I actually received mine yesterday morning in a message on my xbox from LIVE at about 1:30 yesterday and somebody I helped earlier
received theirs at around 4:30 this morning. If you haven't received yours yet just keep an eye out for them. I'm sure you'll be receiving it soon.
Did this solve your problem?
Sorry this didn't help.
Great! Thanks for marking this as the answer.
