Unable to withdraw principal and profits from trading account

I have deposited $750000 to my trading account with SUPER CAPITAL MANAGEMENT LTD on Nov 18 2021.Broker Alisa (+44 7862 581039) helped me to register account. After depositing $750000 I decided to withdraw money on Nov 20 2021. My request has been rejected and I was told to get approval from business analyst Bruce (+44 7898 766346) who declined my request for money withdrawals as well. Regards, Alex Boiko.
