The text message that sent the express threatened me, so call me. What should I do?

Dear, the seller lied to you, you can defend your rights! Objectively speaking, I know that every consumer wants the best service, and this is the best! Besides, I believe that the postman who delivers the express delivery is actually quite hard. It's not good if something that could have been smaller becomes bigger. On the contrary, if we apply for a refund, the money will definitely arrive! And we should return the courier! Please understand that the courier is only the intermediary between the buyer and the seller, please don't lose your temper with them!
