You'll just have to wait, unfortunately. Be careful with these types of companies though...they are like banks. They don't hold your coins like they should, they gamble with it and try to make profits with it. Now while price chart is going up that huge, many customers try to get out their funds and they are simply not solvent enough. You have to wait a couple of hours/days/months until new users added funds to pay you out.
Best of luck!
Yes, I agree, they may just be trying to buy time until they can pay you out. I am not sure how authorities would handle a case like this. It would probably just cause a larger mess than you have now.
