First, it may be that the seller's delivery information is actually correct, but when you click on the computer to confirm the delivery, the single number is wrong, and someone else's single number is filled in your order. Can you just ask the seller if it's wrong? If there is, there is no big problem, as long as you can receive your own goods in two days, it doesn't matter;
Second, it is possible that the seller posted someone else's express bill on the goods that should belong to you when packaging, so that it was sent to the wrong place. Then another customer of the seller must have made a mistake, so the seller will only deliver the goods to you when returning them to the seller, but you can ask the seller to extend your receiving time, and both buyers and sellers should be considerate of each other.
I hope I can help you!
