After not seeing or hearing from anyone within 24 hours of a no show to an appointment I had made to install my opener I left a negative review for Dreikosen. Jeff called me today, 48 hours after the appointment and told me he was in an accident and that is why he didn't call or show up. He offered to accommodate me for the inconvenience that I incurred. He did send me a couple photos of a damaged van to show me that he was in an accident. I obviously can't review his service, but I can say that if I need something again for a garage door I would be willing to give him another shot.
