SCAM BROKER

With no other words then a SCAM broker. After some weeks that i was trading, without a explanation and notice FXGiants just disappear with all my profits opening a false position on EURUSD. After I complain they answer that my trades were off prices from LP, so i am playing in casino or i trade forex? How can i open a position on they MT4 with wrong prices? Thats mean they are fake and pure Market Maker, manipulating prices to their own benefit. On screenshot from them show 491.54$ profits but in reality i made 516.98 and they took all. After i ask for more evidences from LP they never answered back, plus they wanted to charge me 10% administration fee!!! STAYAWAY FROM THIS BROKER...
