I need the HVAC company to clean my furnace

I have been trying to get my furnace cleaned for almost two months ago now.

I was working from my home at that time and I knew that no matter when the HVAC company arrived, I was going to be there. I called two weeks after they were to arrive and I asked when or if anyone was going to show up to clean the furnace. I had a maintenance and repair agreement, so I couldn’t understand what the hold up was in getting the maintenance done. They gave me another date and told me that I had to be home to let them into the house. Well, the two weeks has come and gone and I still don’t have the furnace serviced. I called one final time and I asked what the hold up was on the servicing. I got a lot of excuses about losing two HVAC service techs and how the service had broken down, and I began to laugh. I told them that I wanted a refund for the remainder of my maintenance and repair agreement. She spit and sputtered and promised someone would be at the house the following Monday. I told her this was not going to work for me because it was my first day back at the office. I had no intention of taking off my first day back at work when they had put me off for over a month. I called another HvAC company and they promised they would even show up over the weekend. I guess I am going to need to either fight for my money back or I’ll have to go to court.
