Account manipulation

On Friday the 1st of March I left several pending orders open on different currency pairs and two running order with stoplosses, upon market open on Monday the 4th I found that the running trades have hit stoplosses which I was OK with at first. One currency pair at a time started getting activated and I immediately closed them with profit but to my surprise after I had closed my account was in major loss and no profit was recorded which came as a shock. I decided to check my positions and see what could have gone wrong only to find that all my positions have been moved by Atleast a 100 pips and the stoplosses as well. I contacted the support team and they have since said they are investigating the matter. IC Markets has done me dirty.
