Rejected withdrawal until taxes are fully paide

I need help. I may have been scammed by Vast Forex. At first, I had no trouble withdrawing funds previously. The only time I was prompted to pay taxes was when I reached $20K in profit. I was then advised to deposit the amount equivalent to the taxes owed (4613USDT). So far I paid about half of it and I still owed (2478.25USDT). I tried withdrawing the partial amount of $10000USDT but I was prompted to first resolve the leverage funds. However, this was later clarified in the email as taxes owed instead of leverage funds. I hope that someone may be able to help retrieve my hard-earned money.
