I bought four deadstock belts from vinted for 600€ and got scammed vinted isn’t giving me my money back

Hi! So i bought what was supossed to be four deadstock belts by the brand heavensent, they are originally 50-60€ but i paid 600€ and the postage fees, because they were brand-new with tags. The seller ended up sending me some knockoff ones from shein that didn’t look like the pics, and were still unopened in the shein packaging. The seller is refusing to let me return them and Vinted is refusing to give me my money back. I’m so frustrated because I would never support shein, and it was almost 10 times more money than what these cost.What should i do? The first pic is what I bought, second and third is what I got.
