My account has been banned

I log into my account daily to check out stuff and recently started selling items and have several hundred dollars on my account and I try to log in today and my account says banned for having others rate before receiving and never have I had someone rate me first I believe it was a kid that reported me that was bashing my post because I would not accept his lowball offer and knowing my account wasn’t reviewed I immediately got banned all of my buyers received items and was very satisfied and left me feed back after they received items I have proof in all my messages but can’t obtain them because i can’t log on who can help me?
