Comment: My service window was between 11-1. I received a call from dispatch at about 10:45 AM saying the technician was headed my way. When I asked what "headed my way" meant: Does it mean 10 minutes, 20 minutes, 1 hour, his flippant response was, "I can assure you he won't be there by 11:00 AM." I waited. At 12:34 I called dispatch back because my technician was still not at my home. I was put on hold and told that for some reason the technician had gone to another address and was cleaning there. However, Dalworth did have another crew that was in my area and was available and could be sent to my house right now. That crew was at my house within 15 to 20 minutes and they did a good job. I was given a 10% discount for my inconvenience, which I did appreciate. I did not appreciate the attitude and flippant response of the original dispatcher when I asked about a timeline for "headed my way meant."
