You can call the police, and the police will start the investigation from the bank "Li Pancheng" for you. At the same time, the information you can investigate includes the identity of the owner of this mobile phone number, and you can also ask Tencent to disclose the id and registered ID information of this QQ number to the police.

Of course, if everyone else uses fake ID cards, you can't help it.

Take a warning and be vigilant in the future. In life, there are many slopes, so it is safe to lose money, just as the old people say. No big deal.
