We were assigned Reese HTG &A/C by Sears Home Warranty, which is actually administered by Countrywide Home Warranty. The technician would call and say that he is on his way and then never show up. We called back and he was unreachable. We were told that WE were unreachable, but there were no missed calls on our cell phones or the answering machine where they had supposedly left a message. When we called them the next day, Katy said she knew nothing about it. We were not even on their schedule. Finally the technician came, said your Freon is low, supposedly filled the Freon and they called to set up appointment next week. Again next week, the technician called to say he is on his way, again no show. When we called the call would go to his voice mail. We finally switched to a different company.
