Is it useful for a black cat to complain about Weibo?

Black cats complain that Weibo is useful. Since the black cat complaint is not a market supervision department, it is not binding on the business itself. If the user complains about the black cat, the content of the complaint will be recorded online, which will have a certain impact on the reputation of the business. Merchants who cherish feathers will pay attention to the content of complaints and actively solve problems, and then complaints will be effective.
