How is this a fair perma ban?

So back story time.After a long hard day at work I come home hoping to play a few games then go to bed. I proceed to log in for the first time of the day(8-18-2018). My team picks; yi (who starts being toxic and verbally abusive in champ select) volibear (who was the only logical player on my team that didnt feed or was toxic) Caitlyn (who takes smite mind you) and yasuo (he didn't say much but was mad at the team for intentionally feeding). I picked fizz. we go to lane since cait took smite she goes to blue buff to start the game. voli and yi go top yasuo mid and i proceed to go bot. Cait proceeds to kill her blue instantly comes bot afterwards. Pushes out the lane. Mind you she has smite and no jungle item yet. So she steals the wave from me and gets half gold from it. Then run into the enemy team and dies. I die instantly afterwards. Tell her to go back in the jungle and to get her jungle item. Game continues with cait coming bot and stealing farm from me and intentionally running into the enemy team and feeding without her every buying her jungle item. Also during this game my yi fed 18 kills and verbally assulted the whole team. I'm not usually one to rage at teammates but when u take smite and go in a lane and feed intentionally while stealing farm and gold from your team its tends to not be a fun game. I know my language in the game was uncalled for and I Could have tried to explain to him why he needs a jungle item in a more calm manner But at the end of the day I did not so if me being perma banned for this one game is what u at riot games considers the correct punishment then so be it. But at the same time I would hope that the other 2 kids that were in my game, One who was literally costing his team gold the whole game and refusing to listen or fix the problem and the other who basically ran it down while calling his whole team feeders, Would also get perma banned for this same game. As I see it the actions of the player taking smite on an adc and refusing to by his jungle item or let his teammates farm there lanes is actually more toxic and worst then My language toward said player. Since i cant link full chat logs. All i have for you to see is what i said.

Riot I think your ban system is flawed. And if I'm the only player that got perma banned for that game I would like to know as so I can never play a game where players are allowed to help the other team intentionally win without repercussion. I do not think my account should be perma banned. And I am by no means asking to get it unbanned. But what i am asking for is some information that may help me know if the other players in this game also got punished or if I got perma banned after playing one game where my whole team trolled and intentionally threw the only game i was able to play that day. I would love to keep playing your game but if your gonna perma ban my account because I was toxic towards someone who was trolling and refusing to play the game right. Then I don't wanna play your game at all. also I would like to know what actions are being taken to stop win trading cause it seems as if players are allowed to troll in game and intentionally lose games for others with no recourse or disciplinary actions being taken towards them.

                                                  Sincerely one sad league player who feels as tho he was wrongly perma banned. 

To follow is the chat log from the one game i played that got my account perma banned.
