What if I am threatened by the courier?

It depends on what you want to do. Seriously, my advice is to roll with the punches and roll with the punches. Why are you angry? It's completely unnecessary, and it's not an enemy, is it? Take it. At best, don't use them anymore, right?

If you are really angry, you can complain to your friends and family in turn. Why not use your own number? Just ask your friend to make up a few reasons.

Remember in the future, don't leave your address for express delivery or anything. I usually leave my office. Not particularly important. I didn't even leave my mobile phone number, or I just left it at my friend's house. There's a good reason to contact my friends, right? After a long time, you will have many friends. Don't be afraid to annoy them. Friends always help each other to get better and better.
