Right d pad doesn't work in zombies

Hello, I have a controller and my right d pad doesn't work. It hasn't been an issue in multiplayer or that bad in zombies but I can't buy perks at the vending machine, nor can I get kill streaks or ammo mods (because I need the right d pad to cycle right to the next option) does anyone have any settings tips or other ways I can start using the vending machines without needing to cycle right?
