The courier showed that it had been signed, but I didn't receive it. The courier turned off his cell phone and called the courier company to kick the ball back and forth. What should I do?

Send a message to the courier brother first. He may not answer your phone, but the text message will definitely arrive. In the short message, you explained your close relationship with him.

Call the courier company first and ask them to deal with it immediately. If it is not handled, complain to the relevant departments.

If you still feel too slow, you can call the police directly and let the police intervene in the investigation, provided that the value of the things in your express mail is relatively high.

If you really can't do it, tell the complaints department of their company that I will send a message online if it is not solved.

Mobile phone input, hope to adopt!
