Telephone fraud selling books

How to threaten you. If you reach an agreement with them, you can only pay, but if the goods are different from what you agreed, or even have a major misunderstanding about the goods, you don't have to pay. Theoretically, you should send the book back, and if they refuse, let them go to court to sue. If threatened, take a telephone message to collect evidence and report the case to the public security organ. Whether it constitutes a crime or not, it is a kind of protection for yourself.
