I had a similar experience this past week. My install was originally scheduled for Monday, with an AT&T no show. It was rescheduled to Friday, and AT&T came a bit after 3:00 PM, surveyed the site, and said it would be a bit more work than they thought, and rescheduled. I had taken time off work for both days, and was pretty close to canceling. Last night I got a call from one of the AT&T surveyors, who said they had an install in the area today, and they may be able to come by. Lo an behold, I now have gigabit service installed, thank goodness. While I am very glad to have this installed, had it not been for some luck, I'd have needed to take a third day from work. I understand this isn't necessarily under Sonic's control, but still a bit of a rough start.
