Why does the courier show that it has been signed but not received?

The courier shows that there is a receipt but it has not been received. There may be the following reasons:

1. The courier sent it by mistake, maybe the address was wrong, or it was sent to the wrong person.

2. The courier's operation is not standardized, which leads to the entry of appropriate investment information in advance, or errors in the process of filling in the courier information.

3. The express delivery information is incorrectly filled in, such as the receiver's phone number and address are unknown or wrong, which may cause the express delivery to fail.

4. Others take it by mistake and others get it. This is usually because there are many recipients, and the courier randomly chooses a recipient to sign for it during the delivery process, but in fact the recipient has not received the courier.

5. Merchants use the courier number to brush their reputation. Some merchants may use false courier numbers to brush their reputation, which is actually a fraud.

6. The merchant generates a single bill. In order to achieve the effect of billing, some merchants will generate some false courier numbers and deliver them through courier companies.

7. The courier on the buyer's parcel will destroy the information. In order to avoid personal information being used by others, the buyer should destroy the courier information on the packaging bag after receiving the courier to avoid being used by criminals.

If this happens, you can try to contact the customer service of the courier company or the customer service of the seller to solve the problem. They may help you inquire about the specific situation of express delivery or provide other solutions.
