Compile your online fraud experience and tell the police in detail about the fraud process. The police will investigate and collect evidence based on the information you provide.
If the police intervene in the investigation and evidence collection based on the information you provided and determine that you have been defrauded and the amount of fraud reaches the minimum filing standard, they will file a case and help you recover it.
If you are defrauded on the Internet, you must rely on the police to help you solve the problem. Don't believe anyone who says he can help you. Anyone who says he can help you is a liar. Don't believe it to avoid being deceived again.
