A R P Heating & Air Conditioning

I was charged almost $100 for a lose wire, that I saw when the ARP Tech. took the cover off my furnace. When he gave me the bill for $95, I was surprised and told him that seemed high for just a lose wire. He told me it was $75 for the call out and another $20 for his time. Monday, I called the ARP office and said I think there was a mistake in my charge. The lady told me the first 30 minutes is included in the call out fee. I asked for the Owner, [redacted], to please call me.I received no call from the ARP owner or representative. I called them back on Friday, four days later. The receptionist told me the tech was here 45 minutes and that is the charge. I said, he was not here that long, and asked her, logically would a lose wire that I saw when he opened the furnace take 45 minutes? She was argumentative, unhelpful, and said I could talk to the tech that was here about his time. I told her, I do not need to talk to the Tech. I will relay how my situation is handled with others. It was quite disappointing that for a very minimal amount ARP could have satisfied a previous repeat customer, unfortunately ARP did not have the courtesy or concern to call me back.My service invoice from ARP was filled out by the tech and states, Inspected and found disconnected wire on pilot dutyReconnected wire and furnace started. Test and found system operating properly. A month later the furnace stopped working again. I called another company to come out. I was showed and informed that my furnace heat exchanger was in a dangerous condition due to severe rust, which could result in a fire or carbon dioxide leak.Not only did ARP overcharge me, and not respond to my request for a call back to straighten it out, as a claimed furnace professional, they left me unadvised with a dangerous furnace situation.
