Sorry to hear about the trouble you are having with this bucket shop, I just did a google search and it seems that hundreds of people have the same problem "withdrawing profit" . Even here on this site there are lots of similar complaints, just look at the related threads at the bottom of the page.
It seems that scalping is not allowed "any trade opened and closed under 2 minutes" will be canceled but then your trade shown was open overnight, but it seems from the mounting evidence that making a profit is also against company policy, which s why you will be banned from trading with them, they only want inexperienced loosing traders to trade with them, it seems, just like any bucket shop operation.
I hope you get you money back, I will vote them guilty
