Compleately destroyed my hosting

I’v installed avada theme, made my website, installed these plugin and then started nightmere, wich still haven’t ended.
1) Revolution slider wasn’t working becouse of w3.
2) cache cleaning didn;t effect anything. I was unable to edit something on any page.
3) Wen i got sick of that plugin and error i decided to uninstall it. So i disabled and hit uninstall. but cache wasn’t away.. moreover it gave cached url’s of files.
Then i’v compleatle deleted wordpress and db and installed a new copy ( wich was made before w3 installation ), but even these haven’t soled my problem.
Pages was still cached. After uninstalling wp, i had “index of” page. AND it was chashed to. I’v made changes (uploaded new files) and the haven’t shouwn up.
Then i desided to delete my account from hosting and create new one.. These haven’t solved my problem eathere.
Now waiting for hosting support to answer and fix the mess you’v done!
What’s wrong with you’r plugin ?.. hate it. Not reccomeding to anyone. Burn in hell…
Thanks a lot
