I would give it a 0 but not on the scale. They scheduled a service time window with tech me but they did not show. The service rep said they have no policy in their company that says if they did not find a service tech for your scheduled appointment. And that you can only wait at the end of your scheduled window to find that they are not going to show. In my case I called at the end of 4 hour window and was informed they never sent a technician. Very bad service.
