I hear you. I just posted a similar situation above. Chloe shoes were returned, they arrived to me with tags cut off, worn. tracking only showed scans in my state. return label to me was attached on top of my label to buyer, my packaging. It indicates that buyer shipped directly to me, Tradesy never "inspected" anything. They lied all the way how they inspected the shoes and signs appeared due to my "storage", not the fact that buyer was wearing shoes over weekend and removed the tags. also Tradesy denied looking at the picture of shoes against the label to buyer that show tags attached and no sign of wear. liars.
You can't deal with them directly, you have to file a claim with BBB.
