Hard to withdraw

After applying for a withdrawal, I contacted the customer service and asked them to review it. The customer service replied that I needed to pay the margin. After the deposit was paid, the withdrawal entered the platform, so I withdraw it a second time. The second time I withdraw, the customer service said I was suspected of money laundering and asked me to pay the risk fund, and after paying it, they used various reasons to make me pay the money and not allow the withdrawal.
