Why did Pinduoduo customer service robot send me the previous refund notice as soon as it entered?

Let me know when you surf the Internet. Pinduoduo is the mainstream e-commerce application product of domestic mobile Internet, and it is a third-party social e-commerce platform focusing on C2M group purchase. After receiving the refund information before going online, it is set that offline does not accept the message, so it will be notified after going online. Intelligent customer service robot is the most mature application scenario of artificial intelligence technology commercialization.
