Banned FOr mistaken report leave?

I was banned after a game for a reason unknown to me. I was playing a game and we had a top fiora leave and it was 4v5 whole game. After the game i got a ban e-mail sent saying i left a game. I did not leave, I played the whole thing out, the other player left. I can only see this as a mistake by either someone reporting that I left on accident, or the system made a mistake. And now I am banned till the 15th for no reason. I am sure this will not be fixed, and will be finding a new game in those 15 days hopefully replacing this one fully and I NEVER have to come back to this game again. This is the last straw really, with the attemtpt to reconnect erorr lag, the apparent disregard for responding to problems, and now I knw this "tribunal system" is a joke.

I will have restored faith in riot if they see this and actually do something to fix the problem. If any riot red takes notice to this mistake, they will see im right and do not deserve a ban because OF SOMEONE ELSE LEAVING!!!!!!!!! I do not have access to my e-mail on the account. If a red responds i can give out the new address and you can lift my ban after you see i have done nothing wrong.

I do not expect any response, so surprise me. Keep me as a customer. Show me you have SOME form of customer support. THis is a huge mistaken ban to a person who has played your game for 3 years without any ban before.

Fix this riot.
