There are limited ways to restore Doudian's credit rating because credit rating is very important in the process of operating a store on the Douyin platform. If the credit rating drops, it is difficult to restore it. If the credit rating drops due to poor product quality and customer service, then you need to improve your service quality, make the products better, strengthen the store's customer service, contact customers in person, and try to satisfy customers. At the same time, strengthen store publicity to attract more customers to shop in the store. If the credit rating drops due to malicious behaviors such as malicious bad reviews or fake orders, then you need to negotiate a solution or file a complaint, and at the same time give feedback to Douyin officials to seek help from the platform.
