Plutonium

I'm pleading for my ban to get removed. I turned on some cheats just to find out the end of a map in CoD WaW Zombies. I used the point modifier. I do not know why I got banned for cheating in offline play... I didn't know I could get banned for that, the only other person affected was my friend who I played with since both of us wanted to know what happens when you unlock every door and complete every objective. I seriously didn't know and since it is a big problem will never do it again, I really cant wait 7 days since we play zombies every night. Please remove my ban
