I was originally asked to be home the entire day, then was able to narrow the appointment time to a two hour window because I work too. The service was a no show and I did not receive a call to indicate that there would be a delay or reschedule. I called the company and was told that they scheduled another service in the area and the technician probably went there first, so I canceled the service call and suggested that they call the customer when delays occur and was hung up on, or maybe just got disconnected? A service technician calls me 10 minutes later and I was told that most people don't mind the technician being late and that a two hour time frame is not enough (it was for preventative maintenance to test the freon level at my house). Then why commit the appointment? I suggested that their company call the customer when there will be a delay. Frankly, a phone call to reschedule would have kept this customer. Just plain poor customer service.
