The express bill shows that the convenience service station has signed for it, but has not received the short message. I don't know what to do.

Every express delivery should be a convenience service station.

You go directly to that place, tell them the order number and the name of the courier, and see if there is any.

Mainly because there are too many express delivery, I missed sending you a text message. I've had this situation before.

Also, you can call the courier to ask.
