Zero stars. 10:00am appointment. 1:30pm arrival time. Was told at 10:45 (when I first contacted customer service) that they were “a couple appointments” behind. My second contact with customer service was at 12:45, at which point was told it would be another 45 minutes. I don’t blame the tech: I blame the appointment system. I also am amazed that there isn’t a mechanism to contact customers when technicians are running behind. If I hadn’t contacted customer service myself, I wouldn’t have known that there were “a lot of 10:00 appointments”. So thanks for eating half my day and making me miss my 1:00 appointment. (Which cost me a hundred bucks.)
