At the end of August, someone found me through a friend's introduction to help her defend her rights. He bought diet pills with a self-proclaimed senior fitness coach on WeChat. The other party simply collected some information about the victim's situation, height and weight, reasons for obesity and so on. It claims to be a slimming material specially configured for the victim's situation, and the liar keeps silent about what product it is. Due to the lack of knowledge about consumer goods, the victim did not find anything wrong after receiving the goods. I just feel that it has no effect. I asked her to take pictures of all the products she received and send them to me, only to find that all the products she received belonged to ordinary food, and solid drinks had no weight loss effect at all. At first, I negotiated with the swindler to ask for a refund, but the other party was very disdainful and threatened the victim with insults. If negotiation fails, I will directly complain to the relevant departments, and I will be honest after being complained! Express willingness to take responsibility! I suggest that the victim ask the liar to refund one and compensate three according to the Consumer Protection Law. If the other party disagrees, sue. As soon as the swindlers heard that they would sue them, they had to agree to triple the compensation. Of course, the process is tortuous, and the problem is not so smooth that it can be solved at once. Consumer disputes often involve complex legal issues. We need to keep a firm belief in national laws and not be afraid of setbacks. If the other party starts to refuse, it will be discouraged, and safeguarding rights will certainly not succeed.
