Sorry to hear that, but have you tried to contact them? If you did it already then what is their answer? 11+btc is good amount, usually they need to do some investigation first for big withdrawal amount but two weeks is too long imho. Waiting for FJ to clarify about this issue.
After the first few emails they said it should be completed within a week. Now they just ask me to wait patiently with no information other than "We are contacting mutual investigation, and will update you soon."
Usually, I know that they will take around 10 days to clear these big wins but in your case, it is already more than 10 days. They should have finished their investigation and cleared your funds by now. Next time after you send an email to their support team, immediately post on this thread as well. So that they will take more seriously to clear your funds because everyone will be watching on the status.
