Legal analysis: this is a civil dispute, and more should be brought to court or reported to the industrial and commercial bureau. It's no use calling the police.

Legal basis: Article 120 of the Civil Procedure Law of People's Republic of China (PRC) shall be submitted to the people's court with copies according to the number of defendants. If it is really difficult to write a complaint, it can be made orally, which will be recorded by the people's court and the other party will be informed.
