Consumers purchased Mijia frequency converter DC air circulation fan at the Pinduoduo platform's 10 billion subsidy activity at the end of August 2022 (order number 220831-126804304941273). After receiving the product, I found that the power cord of the Mijia air circulation fan had traces of ablation, so I reported the matter several times to the official customer service of Pinduoduo . The customer service responded for the first time to ask consumers to provide unboxing videos. After the consumer questioned that the Pinduoduo platform’s 10 billion subsidy ensured the authenticity of the authentic advertising, the customer service responded for the second time that the consumer needed to go to an authoritative institution to issue a certificate that the product was second-hand. However, the consumer contacted the product brand customer service and received a reply from the brand customer service that he could not issue a second-hand certificate for the second-hand product. After contacting Pinduoduo many times without success, we hereby remind the competent authorities and netizens to pay attention to it so as not to be deceived! If media friends need relevant information, they can send private messages to themselves. Thanks for help!
