1. Wrong phone number: The merchant may have entered the wrong number when leaving a message, which made it impossible to contact them. This may be due to human error of the merchants or other reasons.
2. Bad telephone signal or network problem: Sometimes the telephone signal may be unstable, or there is a problem with the network connection where the merchant is located, resulting in the phone not being connected. In this case, you can try calling several times or wait for a while before trying to contact.
3. The merchant did not reply in time or could not answer the phone: the merchant may be busy or temporarily unable to answer the phone, or may not reply to the message in time. This may be caused by busy business, time conflict or other reasons.
In this case, it is suggested that customers can try the following solutions:
1. Send a message or leave a message: On the Pinduoduo platform, customers can communicate with merchants by sending a message or leave a message, and ask questions or requests. Merchants can reply to customers and solve problems after seeing the news.
2. Ask Pinduoduo customer service for help: If the customer has repeatedly tried to contact the merchant but failed, he can contact Pinduoduo customer service for help. Customer service staff can help customers communicate with merchants and provide solutions.
3. Consider other purchase channels: If you can't get in touch with the merchants or get a satisfactory answer, customers can consider looking for other reputable merchants on the Pinduoduo platform or buying the same or similar products on other e-commerce platforms.
It should be noted that the above are some common reasons and solutions, and the specific situation may be different due to different business and network environments.
