Permabanned for not being able to hold my anger against trolls...

I don't care about how much money I spend on a good game like this and I'm only trying to express how sad i am because of this.. Yes its a game but its the only game I play and I take ranked seriously. I've spent over 200$ on my account and i can honestly say i'm a decent player and i understand how the game works and how you win. I have tons of games where I average 15+kills and 5 or less deaths and i carry my team for a victory and i bet if you look at the game chat in there you can see how people who are actually trying to WIN the game listen and we have awesome teamwork and i have no intention to be "Toxic" I play to win and that's what im banned for... But then 80% in solo queue I get a troll or i can say a person who just doesn't care what so ever because they don't play league or its their first time trying to use a champion and they do horribly bad. I try assisting them and giving them advice but more than half of the time they take it as insults and start talking so much fucking shit and if they would look to see who started to be toxic and ruining the experience for other people cause by 10 minutes into the game 75% of the time they'll have atleast 5-6 deaths after telling them constantly to just play safe and stay under tower but no I've dealt with it so many times where they just die to other champions over and over again. And the thing that really makes me so mad Riot is that you guys let these type of people report me and rekt by the tribunal system because anyone can ban me and im getting reported by the trolls or feeders who have 0 kills and 15 deaths by the end of the game... Id appreciate it alot if i can get any help with getting this account back with a penalty of like not having the ability to use the chat at all for the rest of my life... Ive had this account ever since like the beginning of season 2 or maybe before i forgot. I really do love this game... I just dont think your system works that well :( </3
