Unable to withdraw fund

Vast forex is scam!!! I can't withdraw my fund from MT5. CS keep asking me to deposit a USDT to top up my account. at first I was able to do withdrawal until i decided to increase my fund and when i was about to withdraw the money i earned there's a lot of fees they asked (Philippines Tax Fee, International Transfer Fee, Green Channel Fee, Profile update fee). Please someone help me to get back all the money I have deposited. I don't have anymore savings.
