Collect evidence of fraud first, and then go to the local public security bureau to report to the police.
Second, assist the public security bureau to go to the bank to freeze the other party's bank card to prevent the other party from transferring property.
Third, if the police refuse to file a case, they can go directly to the court to apply for property preservation, freeze the deposits opened by the bank, and then file a civil lawsuit to demand their return.
Fourth, because it is difficult to protect the rights of online fraud, it is suggested to take legal action as soon as possible to avoid irreparable losses.
