My lol account has been hacked, what can I do there?

I did something pretty stupid. Have passed the security code. But can write with the phone at lol chat (because I'm logged in there). But I can't log in with the laptop. As soon as I log out of the lol app. It is over. What can you do there?

I just think the support contact

Was the account valuable or did it have a special rank?

Well, if the sup does not help, then make a new Acc with more difficult PW
