Getting temporary banned from getting credits and experince

i got temporary banned from getting credits and experience i dont know how i just finished my weekly and daily challenges and i leveled up twice because i got so much experience so i went online to play living dead and i got a notification that said This console is temporarily banned from getting credits can you please help. And without credits i get no experience.

Why not try posting this in the Offical Why did I get banned thread?
