Banned - No reason

Hello all, I have just received this email about 20 minutes ago, ----- Greetings heliumfreak, Actions that have been performed on your account are in violation of the League of Legends Terms of Use. You can review these terms at Due to the severity of this violation, your League of Legends account has been banned until Sat Jan 01 00:00:00 UTC 2203 If you have any questions, contact our Player Support team at Riot Games Player Support ----- and i am unsure what to make of it. I haven't even played a game in over 2 weeks and anyone looking at my match history would have little doubt that i am a cheater. I don't even converse in chat (i generally mute it) so its not like i am banned for being toxic. I am unsure if this is a permanent ban? I am unsure what the 2203 stands for? maybe DD/MM ? Do they not usually provide information when actions are taken? Thanks for any help guys Chris
