i was scammed by instaforex, my case was just like yulia.

i "buy" with 3lot on AUD/USD when market was going to close, and when market opened on monday. i got alot of profit.
i got $445, so i made withdrawal request. but after waiting so long my withdrawal had not been processed.
and when i checked my MT4..i was surprised because in my MT4 there are not history of my order and my profit. that's really strange..
instaforex cheated on me..
i can't accept this cheating sir. i need your help indeed..
what should i do to return my profit?
i will be so please if you would help me..
thanks..
here is my log of transaction

if you could make it all clear i will be so happy..
thanx alot
