Hi, I had a problem.

You have to check emails, check to see if they sent it , make sure that they are the same region as the game wont work unless it the same region

have you checked if you got a message from Xbox Live? it should say they send it. if they have and it's in your email please contact the support they can check it for you as we can only just come up with ways to help ^^

Also make sure this person who bought it is paying for it with the same currency and is in the same region as you.. otherwise it won't work

Yes, it should come as a message in your email associated with your Xbox account. And also you should get a message on your console from Xbox Live with the code and it should let you Redeem it there. If there is nothing, then it sounds like the gifting
may not have went through. I would check with your friend again and make sure that he got some kind of confirmation that the gift was purchased and sent to the correct Gamertag.

If the gift was sent via Xbox Live then you would have received as an Xbox Live message in the message center. I would recommend going there and checking.

If you do not receive the gift then he will need to contact Xbox Support to request a refund on the item.

I suggest u read the description of every product before purchasing it ,
