Just read the reviews on trustpilot.
I've been waiting for a ~9k USD withdrawal to my polish account for the past 30 days.
According to them transfers might/will take 20 banking days.
I didn't ask them to send it by ship or courier, I requested for a simple swift withdrawal.
Stay away from this crappy exchange^.
CEX.io was one of the old exchange site but i can't guarantee that they can fix your issue.
Better to use the support ticket and talk to them to fix your issue. .
