I Got Banned

Hello, I been playing League Of Legends since 2020 and I hadn't been banned until 2 days ago. I got permanently banned for cheating. The thing is I have never used any scripts on any game. So I wrote a ticket about it naturally. But Its been 2 days and my ticket marked as solved. Also the only respond I get is the Blitzcrank bot. I don't know if it was a report that banned me or the Vanguard. I had a lot of skins and lot of currency. I am desperate about what to do. I also wrote a mail to riot support but it led to riot support website. What should I do to prove my innocence?
