I didn't get my specialization code :(

I got the game on the release Date and have been playing since and didn’t get the code. is there any way I can get the code for the? I’ve called Xbox live and everything and they can’t seem to help me

What rank are you?

70, it won’t let me go any higher

I have a code that you can have do you want it?

If you don’t mind giving it to me then yeah! That would be awesome

Btw why don’t you use it on your account?
