Fraud is certain. I have never heard of a regular guarantee company doing this business.
1. Processing in other places, online, or by phone or fax must be a fraud.
2. Using the name of a company to publish information and sign contracts, and using personal bank accounts (those of so-called legal persons, managers, and financial controllers) as collection and charging accounts must be fraud.
3. Anyone who asks to deposit money on his or her card for reasons such as verifying financial strength (repayment ability) must be a fraud.
It may be Li Gui who is pretending to be someone online.
