Consumer complaints should pay attention to the following points:
1. Timely Complaint: When consumers' rights and interests are damaged by purchasing or using goods or receiving services, they should promptly complain to the local department that accepts product quality problems. Complaining in time is conducive to correctly judging the difference between the degree of damage and normal loss of goods, and can explain the situation more accurately, especially the problems related to service quality.
2. Seeking truth from facts: When consumers' rights and interests are damaged, whether they negotiate with the responsible person-the production unit, the seller or the operator, or complain to the department that accepts the product quality problems, they should explain or state the situation realistically, and must not exaggerate, shrink, distort or conceal the truth;
3. Requirements and opinions should be reasonable and legal: the reasons for complaints should be justified, in line with relevant national laws and regulations such as the Product Quality Law, the Consumer Protection Law, and the Provisions on the Responsibility for Repairing, Replacing and Returning Some Commodities;
4. Complete materials: write written materials to the acceptance department when complaining, and provide invoices or sales vouchers when purchasing;
5. The evidence should be conclusive: provide evidence about the damage caused by the product, and provide evidence that the damage is caused by the defect of the product or service.
