FOTUS Card is not working

To keep things short and simple, my code does not seem to want to be accepted by the store. At the moment, I do not have xbox live as I am saving it for the halo 5 release, and on the card it does say that I need xbox live gold membership; however, I’m not sure if this is the case or my code itself is just defective. I have tried redeeming the code both on my PC and the xbox. Any input or thoughts would be appreciated.

I would contact the store you bought the game from and see if they can help you out, alternatively Xbox Live support but they may just direct you back to your retailer

good luck my friend
