The voice sent to me by the chat partner of the store customer service is missing. What happened?

The network is not good. The recording of customer service chat in small shops needs a good network to see. If the network is not changed, it will be invisible. It can be solved by refreshing the network. Customer service refers to the customer service work (accepting customer consultation and helping customers solve their doubts), or the organization that undertakes customer service work. In different industries, the scope of customer service answering questions is different.
