I have been trading for a few months. I made an investment. I invested together with a girl who introduced me to this site. The amount I invested was 6,000,000 Korean won, and the girl invested 7,500 in foreign currency. So we made a profit, which became $320,000. When I applied for withdrawal, they said I had to pay taxes. The girl paid all the taxes and withdrew $250,000. Then she colluded with the company to withdraw money from my account. When I asked for the remainder to be returned, they said I had to put up a $10,000 deposit, refused the withdrawal, and are threatening to freeze my account.
