Cannot withdraw and requires to pay 20% tax

I registered and deposited MT5 through Shenghui Group Ltp (https://www.shenghuigroupax.com) on May 17, 2022. The Shenghui Group trading account number is 211734, so I put 48,402.55 ringgits and once withdrew 310 US dollars; less than a week The final principal profit is 21174.75 US dollars. I will apply for a withdrawal of 9,000 US dollars through the broker customer service on May 26, 2022, but I was informed that I need to pay 20% of the deposit before I can withdraw. I also gave 2,000 payment, I feel that there is fraud and I haven't deposited money. I broke the case number FX1665820480 a month ago. I didn't receive the message He reported again.
