غير قادر على الانسحاب بعد اتباع التعليمات

unable to withdraw after following the instruction

Never provided any information on their website of how much money the account needs to reach for taxes payment of 16%. Although I paid everything that was required from me, which is the leverage that I activated and the taxes which is 12k USD to them in BTC, I asked several times. Now they are saying that I need to pay 50% of the withdrawal amount (30k usd) because the bank needs a risk assessment. My taxes arrived to late and the money will be deposited back to me; what guarantee of it?FRAUD
