Before the start of this order, the buyer said that he needed a slower transportation, so we sent it by sea. We informed the buyer that the order total included the ocean freight, and reminded him that the price was CIF. We also informed the buyer of the transportation time and delivery time. After the goods arrived at the buyer's destination port, the buyer refused to pay the customs clearance fee, did not pick up the goods, and filed a bad review and refund application with the merchant. At the same time, before arranging the shipment, we confirmed the consignee information with the buyer, and he confirmed it. However, after the bill of lading, he changed the consignee name and refused to pay the bill of lading change fee, wasting USD50 and asking for a refund many times.
