I had previously received a code for the one month of free Xbox live gold, sometime in February, for the problems with the MasterChief Collection. I opened the message on my Xbox One but have not redeemed the code yet and now the message seems to have disappeared. I know I did not delete the message, so where did it go? I would like to be able to eventually redeem that one free month. I have already tried contacting Xbox Live support and they directed me here. Help!
