Comcast's Customer Service

After a 2nd attempt to do business with Comcast I am wondering if they are as low in the area of customer service as I think they are. I finally installed Xfinity in December 2013 and am discontinuing it because of misinformation, technical issues, different responses to the same situation, inability o understand what their customer service people are saying as they read and re-read from a script, increased charges for the package that I ordered, and the person I spoke with in another country insisted that is what was ordered (what she saw).  It may have been ordered, but not by me. These are just a few of the problems I encountered.

In early 2013 I had a request for service and cancelled after the negative technician arrived and would not run the cable line. There were other problems as well. I tried again because television reception is poor in my area and I thought having their TV service would provide me with a good, consistent connection.

Did this just happen to be my experience with Comcast on two different attempts? I chalk it up to being a monopoly essentially. The giants around here in the areas of telecommunications seem to be AT&T and Comcast. When there is a monopoly customer service is very lacking, for lack of a better word.
