I bought something online, and the number I left is not in service now. I don't know what to do. The courier can't find me.

If it is your home address and you are at home, just wait for the courier to deliver it to your door.

If you are not at home, you can watch the express delivery from the place where you buy things, write down the express delivery number, and then call the express delivery company and ask them to put it in the residential property or reception room for you. You can pick it up yourself when you have time.

I've never received a call from a courier-they always leave it in the property and leave, so I have to check it every day to see if there is any, so you don't have to worry.
