1, negotiate with the other party to see if it can be returned;

2. Find the consumer market supervision department to solve it, because there are relevant laws and regulations. After a dispute between consumers and merchants, we should pay attention to collecting all kinds of evidence such as written materials in the process of communication and consultation with merchants, so that we can complain to the industrial and commercial departments when negotiation fails, and take legal measures to safeguard our own rights and interests when necessary. Operators who harm the interests of consumers by fraudulent acts shall bear the responsibility of double indemnity;

Fraud here belongs to the category of civil law, and it is an act that an operator deceives and misleads consumers by false or other improper means when providing goods or services, thus damaging the legitimate rights and interests of consumers.
