Fraud platform that does not wtihdraw for customer

I invest and trade MT4 at Zank (Zank International Ltd). Now, my account is profitable, I want to withdraw the funds and the winnings, and then the platform keeps making excuses to ask me to pay them extra tax first with the money. I have told them to deduct platform fees and taxes from my account, but they do not agree to do so. I asked them the name and account details of the tax office where the tax was collected, but they didn't answer. They said that the money must be paid to their platform before it can be resolved. This is a scam and I got scammed by this platform. Please pay attention and stay away from this scam platform as much as possible. Once your money is in, you can't get it back.
