If the junk courier doesn't deliver it to your door, I will call and swear when I complain. How can I punish him?

My Tong Yuan courier here also refused to deliver the goods to your door, and his attitude was very poor. He complained about him. Threatening to hit people at the door is simply lawless. Later, he went to the local Tong Yuan customer service theory, and they said that people were fired by them, and then they called the police if there was revenge. This has nothing to do with them. How can it be irrelevant? It was the courier they used to hire who did such a bad thing. They didn't deliver the goods to their homes, but they also hit people, thinking that being fired would be over. Who dares to use such a courier company? Once the company loses its credibility, it loses its financial resources! Don't use this courier company to mail it in the future! Hire hooligans!
