just been perma banned

i understand that toxic chat is a problems and i understand that there is a mute button however its very hard to stay calm when you have people starting in on you in champ select pretty much every game so yea i was toxic back and prob deserved a ban but not a perma ban especially if you look at the chat it was never me starting it :/ oh well time to grind a new fkn account and lose over $75 of my hard earned money i bet the reason i had so many toxics in my matches is because i wasnt even lvl 30 yet and all the TRUE toxic players where grinding new accounts
