I don't even have Charter cable or internet.  However, I have been invaded by their technicians!  Someone came out for an installation at my neighbor's house least week, and because the cable connection box is in the backyard, the technician came into my backyard.  Apparently, s/he couldn't be bothered to go around my plants, so s/he cut down an elderberry I had planted last year.  There was no reason to cut it down.  I've been trying to call Charter ever since to provide feedback that that is unacceptable behavior, but (of course) can not get through.
