If there is a situation in which merchants cheat consumers in life, consumers can take the following measures to solve it: negotiate with operators to solve it; Requesting consumers' associations or other mediation organizations established according to law to mediate; Complain to the relevant administrative department; According to the arbitration agreement reached with the operator, submit it to an arbitration institution for arbitration; Bring a lawsuit to the people's court. In case of merchant fraud, consumers can collect all kinds of evidence such as written materials in the process of communication and consultation with merchants, and then complain to the industrial and commercial departments for settlement, or they can directly file a lawsuit to demand the merchants to bear the liability for compensation. Evidence accusing the merchant of fraud includes: statements of the parties, documentary evidence, material evidence, audio-visual materials, electronic data, witness testimony, expert opinions and inspection records. The prosecution shall submit a complaint to the people's court, and submit copies according to the number of defendants. If an operator commits fraud in providing goods or services, it shall increase the compensation for the losses suffered by consumers as required, and the compensation amount shall be three times the price of the goods purchased by consumers or the cost of receiving services; If the amount of additional compensation is less than that of 500 yuan, it shall be 500 yuan. The administrative department for industry and commerce shall order it to make corrections, and may, according to the circumstances, give a warning, confiscate the illegal income, and impose a fine of 1 times but not more than 5 times the illegal income. If there is no illegal income, it shall also impose a fine of 1 10,000 yuan. If the circumstances are serious, it shall be ordered to suspend business for rectification and revoke its business license. Other relevant laws and regulations have provisions on the punishment organ and punishment method, which shall be implemented in accordance with the provisions of laws and regulations.

Finally, consumers should also ask merchants to issue invoices or receipts in time during the consumption process and keep them properly. After a dispute occurs between consumers and merchants, in the process of communication and consultation with merchants, we should pay attention to collecting all kinds of evidence such as written materials, so as to complain to the industrial and commercial departments when negotiation fails, and take legal measures to safeguard their rights and interests when necessary.
