I don't know why my account's been suspended for 14 days.

According to the message, "My account's been suspended for disruptive behavior in the game like trolling, griefing, intentionally feeding or deliberately trying to lose the match" I've never played games roughly, no trolling, no feeding. I played my best then how did I get banned for 14 days. Who decides that? Why me? I got camped and there was no way to survive. That was not trolling. Please check this game again and unlock my account immediately.

I was greatly disappointed with Riot this time. This is an over-interpretation and incomprehensible judgment.
