One example. Our A/C has gone out twice in the last two weeks. Of course both times it was on a Sunday afternoon when the answering service took the call. Come Monday morning I had to call again and get in the queue for service. The first time parts had to be ordered (3 to 5 day delivery time). Fortunately, the company loaned us a portable unit for our bedroom so we had some relief. After the same symptoms appeared, a crew showed up and hopefully the problem has been solved.
Second example. We have an internet, phone and TV bundle. When our two year contract ran out, I called to make changes. I asked the person to email me a confirmation. Never received. A month later I called again and left a message. No response. When the contract period ended with no change other than our rate going up, I called again. No record of the changes agreed to. This service person put the changes in place and gave me a confirmation number. One thing never mentioned by the person I talked to earlier: a service person needed to make changes in our house. Now we get to wait two weeks for that. Oh well. Maybe it will actually get changed.
