What should I do if the duck neck of a good shop goes bad?

1. First, you can complain to the industry and commerce department.

2. Secondly, you can collect collections, such as spoiled duck necks, shopping receipts, audio and video recordings, etc. And sue the court for rights protection.

3. Finally, you can entrust a lawyer to submit a lawyer's letter to the other party to warn the other party's behavior and ask the other party to bear the tort liability.
