League of Legends Unfair Ban

Unfortunately, my account on the game League of Legends, which I've been using since the beta version and have occasionally invested money in, got banned today. Unfortunately, my account, which had 330 skins and all champions unlocked since the beta, was banned for what I believe to be an unjust reason. The ban was imposed on the grounds of using third-party applications. I'm disappointed that they haven't provided any evidence yet, and I'm still waiting for their response within 48 hours. If they fail to provide any valid reasons or neglect to rectify their mistake, I'll sadly be motivated to encourage everyone in my circle to uninstall this game.
