I got scammed by someone on this site

I only had one account. Started a couple weeks ago. I bidded on this site. I got 2 lockers. I went and picked them up. Paid for everything. I cleaned out the lockers. Swept them. Got my deposit back. I did everything legit. I gave all my real information and everything.They blocked my account cause apparently I have 2 accounts. I don’t know how someone doing stuff legit would have 2 accounts. I don’t know how I would be banned from anywhere I have my receipts.
