Customer service staff is busy: the customer service staff of the merchant may deal with the problems of multiple customers at the same time, resulting in a slow reply, so it is impossible to reply in time.
Customer service system failure: the customer service system of the merchant may fail, resulting in failure to reply to the customer's questions in time.
Customer's question is not clear: If the customer's question is not clear enough, the customer service staff may need more time to understand the question and give appropriate answers, so they can't reply in time.
Solution: If the phone shows that the other party has not seen it, it means that the customer service is busy at this time, just wait for a reply. If you can't read it, you can report it.
System failure will prevent customer service from receiving information. You can call the customer service center, and the customer service center will move. Just wait patiently.
If the problem is not clear, you can switch to manual customer service and European telephone.
