Commonwealth Appliance Service

Commonwealth were called out to my home for warranty service. The first couple technicians couldn't figure out the problem. Two more came. All were late with no call to say they would be late. When I mentioned the latest I was told that I was rude (for mentioning it) and that this is the way technicians work. Too bad. One even threatened to curse me out over it. When I called the company and spoke to "Bea" she told me that technician, Victor, is the owner's son so nothing will be done. He also ordered parts and left the old parts in my kitchen.
Professionalism does not exist. By the way, my appliance still doesn't work.
