first of all, you are sure that your bid is not brand goods. If it is, you will be in trouble. Now someone specializes in sellers, and he sues you, and you will definitely have to pay compensation. However, if you want money, you will go directly to the seller. I don't know what this person's mentality is. If you are sure that you are not selling a brand, you can provide your purchase order and the trademark right of the manufacturer. But I don't think there are usually any. You contact the buyer and ask him what he really wants. It may be necessary to break the money and avoid disaster.
