Why is it so difficult to appeal a ban?

Ok, before anyone gets mad or is trying to bash my head in through the screen, please, hear me out.
I've tried to sell a card (Otawara, soring City) on Cardmarket. The problem was, I forgot that the card had a little fault; its holographic sticker was missing two marks. It seemed like a typical misprint, and because I got it straight from a booster (my friends saw me pull the card), I thought nothing of it, put it in a ready-to-ship envelope, and forgot about it for some weeks.
Now, because there was a new set coming, I wanted to sell it for new boosters. However, I forgot to add to the listing that it had those imperfections. The buyer got the card and, of course, hit me up because of the imperfections. I (metaphorically) slammed my head against my wall—I couldn't comprehend my own stupidity. Ofc, I apologized and told the buyer I would take the card back and cover the shipping cost.
But the buyer wasn't satisfied enough and now wanted to know where i got it from. I told him I got it from a booster, and the buyer decided to consult his Local Game store instead. The LGS now told him it was probably a fake because the T-test wasn't good enough. I was surprised. Later, without my knowledge, the buyer contacted Cardmarket for a case of a Faked Card. And Cardmarket ruled it was a fake and banned me from selling without letting me explain my side of the story, and I can't even appeal it or get my card back.

Now what can I do? I love MTG and really want to play the upcoming Cyberpunk TCG, but now I cannot sell cards I do not want yada yada yada. I don't want to quit, but the more days pass, the more I want to.
Is there anything I can do, or did someone experience something similar? Are there alternatives? Should I cry and let people throw tomatoes at me?

Thank you in advance, reddit!
