A quick look at their website shows NO information about who or where they are regulated or licenced. The company is all offshore, quote:

This is clearly a scam outfit and their multiple requests for more documents is purely a delaying tactic. These documents (if needed) should have been requested and verified before any money was deposited. I doubt if you will get any money back from them as the purpose of the scam is to steal as much money from people as possible before closing down and re-opening under a different name. The money shown in your account on their website is not real money, just a number. You were most likely NOT trading the LIVE markets but actually trading against their own computer so they can control trades to win or loose as they please. There are many of these scam outfits on the web, CFD, Forex, Cryptocurrency and of course Binary Options! They all work the same and refuse to let customers withdraw funds (because the funds don't exist), and are unregulated and unlicensed. GUILTY!
