Wtf I just got scammed by Dmarket

I was gonna trade on Dmarket, so I trade inn the items I want for something else that was worth like 3 dollars less then what I gave and I sent in my items and Dmarket just starts loading and loading until it asked me to refill my wallet like I dident trade in anything. Thank god for tradeprotectuon but because if dmarket I can’t trade for a fucking month. Thanks Dmarket for ur hospitality and the customer service that doesn’t fucking exists.
