I ordered 3 items seller send only 1 of them. Contacted vinted support and in the end they agreed seller is at fault and told me to get my money back I Need to pay for the return to get my money back from the parcel.. parcel was costing £3 so not worth it paying for the return. But it's not fair as a buyer you pay "buyer protection" which is mandatory and then need to pay for the return when it's supposed to be the seller who is at fault to pay for the return and provide you with a return label.
