i got banned but i did nothing wrong

So i had made a post already but it was quickly removed i do not know why, i spoke the truth so ill try again and see if this one sticks, basically i play league everyday i love and respect it and rage sometimes too but honestly i know im not that good i mean im okay i climbed out of bronze and made it to silver 2 promos but got stuck in silver 3 i have been playing since 8th grade and i am now a senior in high school, league is life now i was playing with some friends in ranked and everything was normal i had a bad kda in a freelo game they had a troll on their team and 2 people ended up basically afk as they complained in base. after we won my end stats screen didn't pop so i closed league and re logged and it said permanently banned due to third party applications or something close to that. now the only games i ever cheated on was like Pokemon when i was little with a game shark.......that is all. in fact i do not even know how to cheat on league i have heard of scripters but never truly understood what it was. i am 18 now and when i saw that perma ban i actually broke down in tears, i love the game and its all i play, i gave up xbox for it and everything just to get a computer to play it on. look if anyone in riot sees this please take a look at the account. if u cant unban it please just tell me what exactly i was using that was cheating. if i cant have my account back i would at least just like to know what i did wrong. please and thank you. avatar8100 is the account
