Without my knowledge or authorization, sent a serviceman to my rental house to re-light the fireplace pilot. I instructed them to send the bill to the tenant who had called them to come out, they refused and cancelled my account. My account with them over the past 6 years was always paid on time though I found the serviceman somewhat surly and some work that was done was questionable. (a replacement part dangling by it's wires from the fireplace instead of installed inside the unit) But, in a small town, not much competition.
