The customer satisfaction survey allows us to understand our customers’ demands. In light of this, we have formulated the Customer Satisfaction Control Procedure to standardise processes for collecting customer feedback and procedures for handling comments, ensuring a timely and high-quality reply to customer comments. After project delivery, we conduct comprehensive customer satisfaction surveys, focusing on service and product quality and delivery efficiency. We collect customer feedback by handing the After-sales Service Feedback Recordand the Customer Satisfaction Survey Form to our customers. We then analyse, track, and investigate any issue arising from the feedback, formulate rectification plans, and supervise the implementation of these plans to continuously improve service quality.
