You are using Zendesk. The way Zendesk works is that when a ticket is initially lodged it goes Open status. If the ticket does not get answered within a certain timeframe the person who logged the call gets a email stating that the call has been resolved, when in actual fact it has not. Example ticket 14552. I can forward you the email if you want proof. I have more. As a matter of fact 98% of all my tickets logged on Zendesk just gets resolved when its not actually resolved. That is why this forum is the only way I seem to get some form of response.
I remember when you guys started, your support was excellent. Unfortunately I think it is a case where your userbase has grown but the amount of support staff has stayed the same and have to many support calls and cant get to everyone in a reasonable timeframe. What escalates the support calls are the continous changes in the core requiring redevelopment by the developers. This not only causing a higher demand for support but also use productivity issues for developers.
Unfortunately, I have too much vested in appery and to change to a different platform provider at this stage is not only suicidal but a monumentous task. 80% of my time is spent on the forum waiting for answers to my problems and 20% actually productive development.
