Everything was great, as usual; BUT! When I make an appointment for 10 o'clock and it's confirmed by the other party the night before, I do not expect or WANT to see the service-person show up at 8:30!!! We are retired, old and frequently do not sleep well, I have not made an appointment before 9:30 since the day I retired 12 years ago and I do not set alarms or get up much before 9. Please do everything possible in the future to assure this does not happen again. Just to be clear, I do not believe this was the serviceman's problem, but a reschedule by the office most likely due to a cancellation of an earlier appointment?
