Have not recieved message regarding Halo 3 ODST

I have been playing Master Chief Collection since it came out and I have still not received a message about a free month of gold and Halo 3 ODST. I was wondering if anyone here can tell me if I will get a message soon or if I should have already received a message. My friends got a message a while ago and I am starting to worry that I will not get a message.

Have a read over this FAQ I posted in the main MCC forums

Some are even delayed, but read what stckrboy mentioned and that should help!
