Can't withdraw money

Recently, I joined a Forex exchange called FSDS Global Limited. At first, there will be 1 person approaching you, then by convincing tricks, you try to invest $ 1000 and have a very good profit, then suggest you to invest more to seize some good opportunity… Just like So, whoever has money can invest more because the profit is real. But signs of fraud started happening at the withdrawal stage. When withdrawing money, FSDS requires you to complete the trading volume (accounts below 10000$ must have 3 transactions with an amount of 50% of the money in the account, accounts over 10000$ must have 2 transactions) . I thought it was done, but when completing the transaction, I was forced to pay a fee of 20% of the total withdrawal amount before withdrawing the money. At this point, I was aware that 99% of this floor was a scam and didn't deposit any more money. Because it is possible that when the other 20% fee is paid, heaven knows if there will be any other reasons or not. The money in my floor is still there, not burned, but now I can't withdraw it.
