This is not right banned from earning xp

All the three reasons you guys gave me for being ban to earn XP was wrong I did not do any of them. I was playing with my 10 year old son in flood and I get a message saying I am banned from earning xp. I thank this is wrong we are paying for this game and for you to ban people that don,t cheat or put there xbox 360s on steroids is not fare. Now the people that do that should be ban because it is not fare for us. Can you please unbanned me so I can level up my guy because I was doing it the right way the way the game is with no upgrade to my xbox or anything just me and only me working hard to up grade my guy Im a level 41 not a level 130 so unbanned me. thank you
