No In-Game Console Message or email received for ODST.

I received an email on June 1st, 2015 to check my IHalo 3: ODST campaign code in my xbox console. Is there an email or support # I can call?

So, to make a summary

If you received an email regarding to the ban and it's permanent and nothing on the console, this means the account has been banned

If you received a message as soon as you connect the console regarding to a ban and nothing in your account/accounts inbox, only the console was banned

If you received a message on the console as soon you connect it to internet and on account/accounts email inbox regarding to ban, both things are banned

Are you talking about the Game Pass promo where you had to play Halo MCC and then received ODST dlc as the reward? I don't believe the code was for ODST directly and more like a $5 gift card code that you could get ODST after. These codes do expire so
I'm not sure when the expiration date/time but you should double check your messages on xbox or even Xbox app on mobile to see if you could still redeem the code.

They are handing the codes out via Message system the console uses for the people who didn't receive the email

I am sorry that you are going through this, remember that I am an independent advisor and I do not have access to your account. but I recommend Check emails or messages from Xbox: Sometimes when an account is banned, Xbox sends an email or message detailing the reason for the ban. Check your emails and messages on the console to see if you received any communication about the ban and the reasons behind it.
