I'm also having problems contacting the support staff.
Did a BTC withdraw 6/6/2017, but it have been "Waiting for Approval" for 1 week and 2 days without any answer to my support message.
I did another withdraw 13/6/2017 which went through like it should.
Also found out that I got "Awaiting for your reply" status in the support message two days ago and when opening it there was no answers left or any actions made.

So hard and time taking thing from staff to do a one click job on the computer and do a manual payout?
