Has this express arrived yet? Didn't you get the message that you signed for it?

It shows that it has been signed for, so your courier has been signed for. If you haven't received it, you can ask your family if they signed it for you. If not, you can call the number left above and ask the courier. If the courier says someone has signed for it, but you haven't received it yet, you can ask the customer service staff of the platform.
