You are suppose to receive it via Xbox Live Message. When the message is sent, you should be able to open the store from another box below the message. However, I feel this may be the wrong forum to post this issue. This is for Halo Wars 2 bugs – look elsewhere. I do not believe you will find the ample assistance that you require here.
