Terrible Installation & Service

I am a new subscriber to Comcast triple play package, although I've been a internet customer for a year. I am having significant issues with the installation and correct functioning of your services. My initial intallation was to take place Friday July 25th. The technician tied in the cable lines into existing cable lines which ran to my roof antenna. He did not give any kind of demonstrations and I was left to make numerous calls to customer service to find out how to work everything. The next day another technician came out to correct the problem and I was told that the lines needed to be "fished" and he was not trained to do this. A third technician came yesterday, stayed about 2 hours and still the service installation is not correct. He complained that he was delayed from other jobs ad called in to ask someone to take his jobs, with a neative reply. He was then rushed to finish and subsequently again, no demonstration about your services. We are now left with certain channels snowy and channels that go on and off, non functioning internet, which we were able to get working again after paying $39.00 to our router company because we thought it was the router and not the modem, which had been disabled prior to the technican leaving and cable wire and litter left from the completed job. We expect the 4th technician tomorrow. If things aren't rectified, I'll take my business elsewhere! They seem to use both their own technicians as well as contractors, they tend to overbook them and they feel rushed to leave to the next job.

JUST AN UPDATE TO THIS COMPLAINT... Comcast contacted me right away after this complaint was also sent to them and rectified the problem .
