The courier called me after delivery and told me to send him a text message, otherwise he wouldn't take the courier away at the collection store?

Hello, you have made this matter very clear. It can be seen that you also realize that it is your own (friend's) fault that caused this problem. Now you ask others if they want to complain, but you don't want to hurt others easily. This courier's practice is also quite professional, and he didn't do anything to your courier, which shows that he is not a villain. However, this courier always makes texting too annoying. I think it's no problem to cure the enemy first. You must have been too modest before. You can explain it to him. Always sending messages has caused you trouble. You promise it won't happen again. If so, what will happen? You are willing to send messages every time in the future, otherwise you will complain to him. I think this kind of thing can be told directly to him. Of course, we should pay attention to the words and avoid conflicts.
