Is there anywhere, where I can report a false ban?

I'd like to report a false ban please, I stopped playing the game a little over 2 months ago and forgot about it completely untill I went through my Steam Library and saw the game sitting there and I decided I want to play online while lockdown is in action, but when I wanted to go into my favourite online server (Which is Leafos), I got a message that said that I was banned forever for hacking, but I honestly do not recall doing anything like that. If the person who banned me, could just explain to me what events occurred for me to deserve this?
