Unable to withdraw money (the service provider’s broker requires a margin)

After paying the dividend on December 7, the cash withdrawal was refused. On December 8, the cash withdrawal was refused. It was said that the capital account was frozen (the reason was suspected of involving money laundering). The corresponding deposit was immediately withdrawn from the account. The second supervisory bureau investigation confirmed that the account was empty. Money laundering can be withdrawn (about 1-3 months). Yesterday, December 20, AdenMarkets Doo Manager Lin said that cash can be withdrawn. The capital account has been confirmed to be free of money laundering. Now you need to pay a deposit of 15% before you can withdraw. I don’t understand why I need to pay a deposit before I can withdraw money even if my account is restored.
