I scheduled and appointment with them and on the morning of the appointment, I realized that I would not be available at the scheduled time. I called them right away and explained what had happened. They were so nice and asked if I would be available later that afternoon. I told them that I would, and the immediately rescheduled their own appointments to accomidate me and my mistake. They arrived on time and were very quick and friendly, not to mention the price was the best one I had found in the DFW area. I hope that I don't need to replace another glass on my vehicles, but if I do, I know I will not be calling around for the best price, I will be calling only Greenville Auto Glass.
