VAST FOREX: A SCAMMER (DEAL OR NO DEAL)?

I invested $5330 at Vast Forex. I was so happy when I got my first earning which was $270. I continued to increase my Funds and do the trading using MT5. Until I used the leverage. The leverage helped me to earn almost $77000. When I decided to withdraw my earnings, VAST FOREX tried to hold my earnings. I received an E-mail from VAST that I need to pay my tax amounting to almost $10000.
Until now, I can't withdraw my earnings for Im not capable to pay my tax. Praying that someone could help me get my earnings from Vast Forex :( ;(
