If the temu buyer does not reply, first confirm whether it is due to other reasons, such as system failure or network connection problems. If it is confirmed that the buyer has not replied, you can try to contact the buyer through various channels, including repeatedly sending messages, calling or emailing. In addition, if there is no reply for a long time, you can consider contacting customer service or the platform to file a complaint. The most important thing is to maintain patience and communication, respect the buyer's work and time, and believe that the problem will eventually be properly resolved.
