After four messed up and missed appointments (on Frontiers part) in February, we had to reschedule for April when we returned to Dallas. This time everything went like clockwork. The service man called ahead, was on time, explained everything, and had the system working within the hour.
My WiFi connection goes out every 3 days and I have to wait atleast a week everytime before a technician is able to come fix it. Very aggravating when I still have to pay full price for my service.
