Why didn't the prescription drugs bought in JD.COM show the logistics information?

The reason is that the merchant submitted the logistics information on JD.COM, but did not deliver the goods to the logistics company. There is no logistics information, which means that the logistics company didn't scan this single number into the system, because the merchant submitted the logistics information on JD.COM and didn't send it to the logistics company. The merchant filled in the logistics information incorrectly, and the logistics company did not scan the received items in time. Logistics has been prompted to send to a certain place, and the logistics information has not been updated for several days. The reason is that the logistics destination is remote, the intermediate delivery time is very long, or the logistics company is inefficient at the peak of express delivery, and the goods are lost in the delivery process, generally more than 65438 pieces.
