What if the logistics shows that it hasn't arrived yet but has been signed for?

First, let's see if there is any express mail in the property mailroom. If not, you can check with the courier whether the information has been sent to the mailroom.

Second, if you don't get the exact delivery content, you can complain, especially if it is not delivered to you without notice, you can complain directly.

Third, the delivery is not delayed if the courier does not arrive.

Fourth, if the courier does not accept the complaint, for example, if it is not solved quickly, he can complain directly to the State Post Bureau, which is in charge of all couriers. If the complaint is successful, the post office will fine the courier as a punishment.
