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."
At the end of the week it will be a month I have been waiting for my withdrawal. I have been patient. If I have not been paid by the end of the week I will open a scam accusation thread.
