I got involved in online trading with Tradersroom.com. At that time, they had a promotion, which they called bonus that if i deposited $5k, i would get $2500 bonus. When i realized i was losing all my money and had $5029 in my account with Tradersroom, and wanted to withdraw the money, they told me i needed to leave $2500 of the bonus. They did not specify, at any time, that the such called bonus was in reality a loan. Now i am losing this money that i pretended to invest for college. What can i do?
