Credit card deposits are one of the few lines of defense.
If you did deposit by credit card, gather up all the info you can as fast as you can (there are deadlines). Call your credit card's issuing bank. Ask to speak to someone in the fraud department. Explain exactly what happened, how much money you put in and how much you've managed to get out (if any). Explain that withdrawals are one of the services a brokerage is supposed to offer. Ask if a chargeback for failure to perform promised services is an option.
Do note: If there was any profit, a chargeback cannot recover that. It only covers deposits. From what I've seen, getting one's deposit back is about the most that can be hoped for when dealing with UFX Markets.
