Fraud platform with no conscience

On June 25, 2022, I made a deposit of 3,001 US dollars under a group of people who fooled me. I transferred 20,100 yuan in cash to Alipay to him, and then made the deposit on my behalf. I applied for a withdrawal on 2022.9.26, but it has not been reviewed. Ask why. I have been saying that the system is upgraded, let me wait, and now I am requesting to return 20,100 yuan in cash, otherwise I will call the police and seek legal weapons to protect my rights and interests.
