SF Express didn't receive phone calls and messages. What if the courier loses the doorman?

You should find SF Express and contact customer service to respond. The courier company will help you solve it.

Besides, is your courier a valuable item? If so, you can find the property to check the monitoring and see who took it.

Or call the police.

It must be annoying to encounter such a thing, it's New Year's Day. Take your time.

I hope you can solve it smoothly.
