Warning. They are fraudsters. It works so that when you respond to an advertisement (car, motorcycle), the alleged seller will contact you and inform you that he has a contract for sale from a company that will contact you and deliver the goods to you. You will pay the broker and only after your confirmation that everything is ok so the money will be paid to the seller. They are fraudsters. Definitely don't pay anything. They don't deliver the goods and you lose money.
