Hello, in practice, no matter how much money is defrauded, the public security organs should file a case for handling. If the amount of fraud reaches 3,000 yuan, it is a criminal offence and is under the jurisdiction of the public security organ, which shall file a case for investigation. However, even if it does not meet the criteria for filing a criminal case, it is also a violation of public security management and belongs to the jurisdiction of the public security organ, and it should be filed for handling.
So you can call the police!
There are many liars these days, so be careful. I hope you can find your lost money!
