I'm in a similar position. Deposited 10k USD using international wire transfer on the 15th October. Send in SWIFT copy proof of transfer but they simply won't reply to my support tickets. In fact they've just closed my ticket and still no response.
I created a fake account on monday and asked support how long withdrawals take, got a response within 5 hours. When I asked why they aren't responding to my other account.... Silence.

They are trying to steal my money.
