1. How to compensate for the wrong food in the supermarket (1) If the supermarket price does not match the actual price, you can complain to the consumer association and ask the supermarket to compensate the consumers accordingly. The increased amount of compensation is three times the price of 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. (2) People's Republic of China (PRC) Consumer Protection Law; (3) Article 20 Business operators shall provide consumers with true and comprehensive information about the quality, performance, use and expiration date of goods or services, and shall not make false or misleading propaganda. Second, how to protect the rights by spending more money (1) From the content of the complaint, there are three main situations in which the supermarket overcharges: First, the actual checkout amount is slightly higher than the marked price; Second, the "promotional price" is actually charged at the original price; Third, the same commodity is charged multiple times, that is, a commodity is scanned multiple times. (2) The new consumer law stipulates that if a business operator commits fraud in providing goods or services, it shall increase the compensation for the losses it has suffered according to the requirements of consumers, generally three times; After the compensation is increased, if it is not in 500 yuan, it will be in 500 yuan. Judging from the acceptance situation, consumers have safeguarded their legitimate rights and interests through the new consumer law. For example, Yu bought two cans of potato chips in a supermarket, each at a price of 5 9 yuan, payable to 1 1, 8 yuan, and the supermarket paid 15, 8 yuan. Later, he complained to the industrial and commercial department and obtained compensation from 500 yuan. Another example is that Gao bought 9% toothpaste from 7 yuan, and later found that the supermarket overcharged 3% toothpaste from 2 yuan. With the intervention of industrial and commercial personnel, 500 yuan was also compensated. (1) Find the administrative department for industry and commerce, the quality and technical supervision department, the consumer association, the competent department of the enterprise, the commodity inspection department and the people's court. (2) The so-called consumer complaints refer to written or oral objections, protests, claims and requests to solve problems raised by consumers in order to meet their daily consumption needs because of disputes with operators in purchasing or using goods or receiving services.
