Cannot withdraw. Withdrawal requires to pay personal income tax

In MetaTrader 5, I followed my friends (netizens) to trade forex in IH global market limited. The first time I use it, I could make deposits and withdrawals normally. On the second time, the customer service ask thirty thousands from me to trade again and the netizens lent me 20,000 (think about it now. Why so naive), the money is enough for 30,000. The transaction was completed two days later, with a profit of 14,000. When I want to withdraw cash, the customer service said that I can't withdraw it, and I have to pay 20% personal income tax, which is more than 8,000. Hearing this, I know I have been scammed. The money is not much, but it is my savings. There is also the tuition fee included, the hard-earned money. I want to try if I can get the money back. I hope everyone could be vigilant! I also hope that the platform will expose this fake platform!
