Asked this man to come to the house on a Monday, called on Saturday said he was just around the corner on another call. Charged me for a emergency weekend call. Destroyed my oil burner by installing wrong parts that he knew were wrong, I witnessed this when his assistant questioned him in front of me. Almost killed us when the boiler blew the vent off, by excess fuel in firebox. Hung over drunk, looking for some easy money. Defecated himself while working, used our bathroom to clean up. I spent hours disinfecting and cleaning after he left.
