Why am i being Banned?

This e-mail is concerning my account Academy Garen. The e-mail that Riot has sent me says I've been banned for getting boosted. Contrary to your belief I have not been boosted. If you take a look I’ve played a lot of games to get gold and I was gold in the last season. Also my rank is not even that high. For what reasons do you believe i was boosted? Where is your evidence? I would like you to please re-review my account because I actually played to get gold. I don't understand why I'm getting banned. I've played many so games to get gold. I just don't understand how you came to the conclusion that I was boosted. This is really unfair. As a “leaguer” and gamer I have been offended by this accusation. I have have spent over 100 hours on league and hard earned money to buy the awesome skins that Riot releases for its champions. This game was my gate to Mobas and it also changed my view on MLG. The World Championships got me pumped to try and get as good as the players participating throughout the tournament. People like Faker, Dyrus and Doublelift truly inspired me to try and get as good as them. If this is not fixed or if i am not even notified that Riot has seen this and responded within a reasonable amount of time, I am not sure that I will return to the game I love to play known as League of Legends.

Thank You, Academy Garen
