Shipley Energy customer service is surly, rude and unresponsive York, Pennsylvania

This company has been very unpleasant. We signed up for oil and then agreed to their service plan. Our oil furnace was not working. They sent someone out to fix it. Someone showed up early in the morning. He knocked and then left without even giving me a chance to get to the door. I went to both doors of the house looking for this person. I could see the truck parked on the street so I got my shoes to go outside and look for the person. Just as I opened the door to go out, I could hear the truck drive off. I immediately called the Shipley company and said their truck had just driven off without waiting even 2 minutes for me to get to the door. They said they would send the person back. Nobody came back so I called again and they said he would come back some time today. By the way, every person I talked to on the phone was extremely rude in their tone. I got a lot of comments like, "Well, ma'am, this is a very busy time of year for us so we are booked up for more than a month." Well, don't sell me your 'service' plan if you are unable to give me any service! Are we supposed to go a month without heat?! By the way, you are never allowed to speak with the department of the company in question. You always speak with someone in customer service who will pass the information on to the people who can actually do anything. They always promise to do things but nothing ever happens. We were promised that someone would come to our house again that day. Nobody ever showed up or called us to explain why no one showed up or to reschedule. When I called to cancel the service plan because no one showed up, we were promised that that information would be passed on to accounting. We have yet to see a Shipley service person but Shipley has been billing us for a service plan every single month.
