1. Keep relevant evidence: collect evidence related to fraud, including contracts, receipts, communication records, etc. This evidence helps to support your complaint and rights protection process.
2. Call the police: report the case to the local public security organ immediately. Provide detailed descriptions and evidence materials so that the police can investigate and deal with fraud cases.
3. Complaint handling: complain to the local administrative department for industry and commerce or the Consumer Council about the company's fraud. Provide detailed information and relevant evidence for relevant departments to intervene and help solve problems.
4. Seek legal aid: If your loss is large, you can seek legal aid. Please consult your local lawyer or legal aid agency to find out what legal measures you can take.
5. Prevention first: strengthen self-protection awareness, improve identification ability, and avoid trusting unverified information before cooperating with the company. For important business activities, due diligence can be conducted to understand the company's reputation and operation.
In different situations, the solution may be different. I strongly suggest that you consult local government departments or relevant legal experts for more specific and practical advice.
