After-sales return visit service

After the customer signs for the parts and confirms that the installation is complete, the system will automatically send a follow-up questionnaire on the 3rd, 7th, and 30th days. The content includes the experience of using the parts (such as whether the screen display is clear and whether the battery life is up to standard), whether the installation process is smooth, and satisfaction with customer service. For customers who have feedback problems, customer service will proactively contact within 2 hours. For example, if the customer reports that the battery life is not up to expectations, the customer will be guided to perform battery calibration. If the problem is not solved, a return or exchange will be arranged immediately; for customers who have difficulty in installation, the problem points will be recorded and subsequent guidance tutorials will be optimized. Based on the suggestions collected through follow-up visits, we will regularly update the service process. For example, based on feedback from many customers, we have added a “Senior Phone Model Matching Guide” to facilitate the purchase of elderly customers or their children.
