1. The human customer service was not contacted. This is the most common situation at present.
2. There are too many customer service receptionists, or something is temporarily not in front of the computer. Some big shops have a large number of inquiries and a limited number of customers, so the reply will be slower. People are in a hurry, and customer service won't sit still in front of the computer all day. If the customer is temporarily away from the computer and you just come to consult again, you will not be able to reply in time! If it is a relatively large store, this situation will generally not last long. The customer service will come back in a few minutes or ten minutes, and will reply when you see the information. There are also some small shops that have no professional customer service and part-time shopkeepers, and may not reply to information in time. Generally, if the customer service ignores people, you can wait patiently for a while. If there has been no reply, it is recommended to consider changing to another store.
3. There is something wrong with the professionalism of customer service, and I deliberately don't reply. This kind of situation is generally rare. According to the normal situation, both the seller and the customer service invited by the seller should receive the buyer's consultation. After all, for customer service, if you can clinch a deal, you will increase your performance and get more commission. This is their job.
If you contact the customer service for after-sales problems, the customer service fails to reply, or deliberately fails to solve the problems, you can prove and complain to the manual customer service.
