I set up an appointment with these folks four (4) weeks ago. On the day of the appointment 7/17/2017, they were a No-Show. The funny thing about this appointment, I had an arrival window of 12 noon to 5 pm and they couldn't make that. Then some lady called at 4:32pm to tell me the technician was on his way. At 5:10pm, no technician. How long does one wait after having been scheduled 4 weeks ago? No thanks, will stay with my regular company.
