Wrongly Ban

I personally think I was ban for my last game, the reason why I "raged" some may say, during the game it was alright my Bottom Lane was still trolling and I had to tell them to stop and play better. For some league creators you may say its unsportsmanlike, I see it as making others better. Thus, on to my last game it was around 45 minutes when my teammates kept trolling the team, I don't know what I should of said but I think my actions were correct because if you were in my position what would you do? This was my last promotion game by the way, now during around 45 mins my Morgana that was on the team kept on 1v5 around a critical point in the game were 1 death equals baron. After that ordeal I started to tell my team to play better, turtle and try to survive for the baron to run out but then morgana and her duo lucian starts to go guns blazing and die and made us lose the game. Personally I wouldn't want other players to be playing with these players because they are going to get trolled and lose. Waste of time and then they would get ban for afking from the trolls its a cycle of hate and trolls.
