Perma banned?

I have been banned for more than 24 hrs. I quit a couple matches and have been temporarily banned before. Lost a ranked match a few days ago the match ended and randomly popped up saying i disconnected from the match even though the match was already over I did not quit or disconnect the match clearly ended. I was then banned for literally no reason. This is a very harsh banning system im all for bans but never a permenant one.

Please don’t cross post topics thanks
