You could also try tweeting to the C-Cex twitter account here for support, though it seems most of their tweets are plagued with other tweets about horrible support and such. Seems like a terrible exchange overall from what I can see.
I don't think twitter is a good option I don't see any response from C-cex, almost all user on C-cex having the same problem like disabled support ticket. This is an old issue and this is still happening again just like before.
I think the best thing they can do now is to wait for more days if they don't receive any response about the issue then start a scam accusation about this exchange so that the other user can be aware of the C-CEX issue just like the other did here before.
