Balzer's Heating & Air Conditioning

On January 7 I paid Balzer's $179 for a maintenance agreement to have a spring air conditioning checkup and in the fall a furnace checkup. I did receive a spring checkup, but not until a few weeks after I called asking why I hadn't received the spring checkup yet. I never received a fall furnace checkup. I called Balzer's a few weeks ago asking for a refund of half my money, $89.50, as I did not receive the fall checkup. I was told they called several times with no answer. I'm retired and babysit my grandkids, so I'm home most of the time. I only had one message on my answering machine saying they would be in the area if I would be home to do the fall checkup and to call back if I was home. It so happens I wasn't home. That was the only call I know of. I do have an answering machine, so a call could have been made to schedule the checkup. When I called a few weeks ago, it was offered to do a checkup this spring or fall this year. I said I wanted a refund of half my money; I was told that would have to be approved by the boss. It has been a few weeks and I have not heard anything back from them.
