can't withdraw

I transferred 30% of the account balance as compensation for money laundering and tax evasion, which was listed as a withdrawal condition. However, the withdrawal request was rejected. They said that there was a suspicion of illegal transactions and that they could not withdraw money unless they transferred 15% of the account balance under the name of security deposit for illegal transactions. I am distrustful of being asked to make an additional payment under the pretext of hearing it for the first time. The 30% security deposit has not been refunded and the funds are still tied up. Please solve it.
