The method of applying for after-sales service on Doudian mobile app is as follows:

Doudian can help buyers fill in the return express number, and the merchant handles the consumer's application (1. After the merchant refuses, the consumer's application enters the waiting for consumer confirmation state. If the consumer continues to apply for customer service mediation, it enters the customer service mediation process. If the consumer does not apply for customer service mediation intervention within 7 days, the after-sales service ends; 2. The merchant must handle the consumer's application within 48 hours. If it is not handled within the deadline, the system will automatically agree to the return).

The consumer fills in the return order number and sends the goods back (if the logistics order number is not filled in within 7 days, the return process will be automatically closed). The merchant confirms receipt of the return (the merchant must confirm receipt within 7 days after the consumer uploads the logistics information. If the operation is not performed within the deadline, the system will automatically confirm receipt).
