If he is really useful, it depends on the reputation list. If a company's product quality problems are on the list, then public opinion will supervise it. At present, official channels are still useful for complaints. After all, the government has the power to enforce the law, and other third parties have supervision by public opinion. 3. 15 Now that businesses have formed a routine, I am not optimistic about the public opinion supervision of third-party media. From Lao Luo's Siemens refrigerator to Apple's replacement of the back cover, there is only one-year warranty, and then to Samsung's explosion door, Lenovo's broken shaft door, and there is no China in the global recall of various automobile industries. These are great public opinions, which have been solved for a long time, and also prove that everything that can't really harm him in front of capital is a paper tiger. Therefore, I don't like black cat complaints. It is suggested to seek the support of official institutions as soon as possible. They have the power to enforce the law and can punish enterprises. Enterprises can only solve problems if they are afraid of punishment. Third-party public opinion supervision is always only aimed at large-scale quality problems, and many enterprises can play dead for a long time before attracting attention. After all, everyone is forgetful and bought it in a few days. Only administrative or civil punishment can prevent enterprises from committing crimes again.
