The supplier initially claims that the product is in stock. When you pay the advance, you are told that the goods are not in stock and they will produce them in 2-3 weeks. We pay in January and receive the product in May. We indicated the country and port of delivery, but the cargo was sent to another country, we had to pay extra to get the cargo to the correct addres. The seller doesn't admit his mistake once you've paid, he doesn't care what happens next.
