I deposited money with BravoFX Markets for trading. After making profit I requested a withdrawal but the broker is not processing my withdrawal.

I deposited $800 to BravoFX Markets through Binance (USDT). My account ID is . After trading I requested a withdrawal of $400 but the broker has not processed my withdrawal. Currently $753 is still showing in my account. The IB who introduced me to this broker also took $150 from me promising to help with the withdrawal but nothing happened. I have proof of my Binance deposit and screenshots. I believe this broker may be delaying withdrawals and possibly operating fraudulently.
