Regarding the codes for specializations

The email for my gamer tag actually does not exist anymore and the codes for the halo 4 specializations for my gamer tag will be sent to nothing I actually want to tell 343i or Microsoft itself to help me about it because I can still use the profile but I don’t get any codes or things for it through email at all can any one help me to contact 343i about this

This would be something you would contact Xbox support to change your email. You better do it quick because they are not resending it…
