Banned due to platform abuse

Hello faceit, I have played almost 5000 matches on your platform and bought premium for the first time and planned to do so in the future and just got banned due to platform abuse. On what basis? I don't play with cheats, I don't upgrade anyone, nobody upgrades me either, I always play alone, every game, you can check every demo for cheats or prohibited programs. Please look into the situation, this is a mistake. Thank you
