Halo 4 Global Championship codes disappeared

Hi this is for the moderators as request by xbox live support team , i received a message from halo giving me three codes for armour for playing in the championship , i opened this message yesterday however i didn’t get the codes out of it and it is no longer there , xbox support asked me to post this here so you could track down what was sent to me and resend it .

My xbox live name is nevereleven

Many thanks in advance
