Excuse me, does the courier have a rule of not calling or texting?

Usually it is sent to the courier station, and the courier at the courier station calls to send a text message, but then you can complain that he didn't call the courier because the courier has already delivered the goods. This courier is responsible, because he delivered the goods himself, and if it is not delivered to the customer, it is his dereliction of duty. You can complain that the courier company asked their company's top management to solve this problem.
