League of Legends Banned My Account Unfairly Despite No Use of Scripts or Third-Party Tools

I’ve been permanently banned in League of Legends despite never using scripts or any third-party software. I’ve never even been curious about such things. Meanwhile, the game is filled with trolls, intentional feeders, and SC players who never face bans. I’ve even seen players who were previously banned for cheating return to the game a month later.

The ban system feels unfair and ineffective. My account, which I’ve built over six years and invested money into, was banned without justification. I am confident that I never cheated and request a thorough review of my account. My time, effort, and money have been wasted. Please assist me in restoring my account and correcting this mistake.
