Scheduled an appointment to address a serious electrical problem - they told us 12:30 to 1:30 arrival. No word by 3pm. Called them at 3, and they said the guy would arrive at 4. At 5 the electrician called us to say that someone would contact us the next day to reschedule.
Short story: I wasted a day at home waiting for an electrician who never came. The need to reschedule is understandable and acceptable, but not after I've waited at home the entire day. At 2 or even 2:30pm, you should have already called us to explain that he would be late or to reschedule. I will post this as a warning to others to avoid your company.
