When you don't have any active licenses (i.e: all your licenses are suspended) you can't open tickets with the Support Department, since you basically have no active support package. We do have automatic e-mails going out for this type of cases, to let you know about it.
It's a bit inconvenient, I know, but you are able to open tickets with the Sales Dept. to help you out (which you did and then you got a reply within 15 minutes) As for your billing issue, I'll personally handle it today during business hours.
whose responding to tickets at centova?
