Lack of Support for My Situation on Appointments+

I was told I'd get help with setting up several functions.php hooks to eliminate my needing to hack the core. After I was told to setup a mirror site and report back, I have not received any word. 3 days have gone by and I'm starting to think I've been dropped. How should I feel?
