what do i do now i am banned and and cant play any tournament {i am not able to joi any tournaments}

Yes, I have the same thing in my account lichess.org/@/IVAN_SERGEEV2010

Top of ToS:
-> Do not cheat or receive assistance in games (from a chess computer, book, database or another person).
-> Be nice and courteous to all other players, always.
->Do not make multiple accounts.

when you lichess.org/appeal ask for another account and say if you have cheated or not wait till they replay and don't close that tab and don't play chess only write in english

ask your parents for help

i wrote 2 weeks they didn't write anything

So you played a rated game less than 24h ago, yet you wrote 2 weeks ago about your ban? Just a tip, be honest in the appeal process about your violation (maybe you manipulated your rating?).

look www.bing.com/images/blob?bcid=SyrxKL7KXyMDDw

it's you
IT IS SHOWING LIKE THIS ACCOUNT IS VIOLATED BY LICHESS TERMS OF SERVICE

@davkridakendram43 you played this game in a rated tournament less than 24 hours ago which you wouldnt be able if you were banned:

Just go to lichess.org/appeal, as others have said. It will tell you why you are marked and it's the only place where you can get any more information or get this resolved.
