IVe been forced to summit and riot dosnt want to help

I have been perma banned riot says i use script yet i have never used anything in such way of a third party app to help my gameplay besides lolsumo and lolking but apparently i have used something worse but they have no proof of me cheating and i can even prove my innocence they don't wanna even hear me out. ive spent not just money but countless hours being hours of anger bc of ranked or from enjoyment with my firends and now i am being forced to never play my fav game again just bc of a faulty system.
