Unreachable Customer Care

I have tried  to reach customer care numerous times on various days, without success.  I am beginning to wonder if the monitoring service actually works.  The first day I installed the system I was able to speak to someone, who made an appointment to call me back the next day at a certain.  She never called, and since then no one answers the phone.  I am beginning to have second thoughts about the system.

Best time to get someone is in the morning, at 9 am (ET) when they first open, then press #1 for sales, someone should answer sooner.
