What should i do?

So i recently got another perma ban for using 3rd party modifications (i think because of using the replay HUD in overwolf because i installed the program and got banned the next day). This is the second time I got banned "scripting" when i dont script, when I ask what programs did i use or give me proof they just ignore it and close my threat i dont know why riot would do this i spend arround 500 euro in total on league of legends and they banned me twice. Is riot games just a %%%%ing money whore who just ban normal users that spend alot of money on league to get more money? i hope any rioter wil see this and help me get unbanned. untill than ill always be trying to sue riot games or to get my account back on my own.
