The courier arrived, and people sent me a text message to pick it up. I didn't notice that my phone was silent. It's past time now. What should I do?

Call back! You can also check the phone number of the local post office online, call the post office to ask where the courier is, and get it yourself! If it is a courier company, call the local courier company. If you don't know the telephone number, check the telephone number of the head office and ask the branch online. Step by step. Of course, I usually send it to you the next day. If you don't pick it up in a few days, I'll give it back to you.
