Why can't Comcast do an HD install the right on the 2nd or 3rd try?

On the first installation attempt the tech brought the wrong HD box because Comcast never told the contacttor which box to install. On the next attempt, the box with the right connections was defective because the box and remote would not talk to each other and so, could not be installed. After wasting two Saturday mornings waiting for tech to not install the HD box, a third appointment. All went well, althought the tech had problems getting the remot to talk the box. Later that evening, the remote stopped talking to the box so I called Comcast again and was told the earliest Saturday available was in two weeks later. I called to confirm the appointment a few days before it was to be and was told that they cancelled it due to the fact I had no signal at the house. I was amazed at this remark becaeuse we watched TV the night before and told the rep that it was only the problem with the remote talking to the box, the signal was fine. The right hand does not seem to know what the left hand is doing or just does not care. This ordeal has been going on for two and a half months and we would switch to satellite if we had line of sight but we are at the mercy of a company that just does not seem to have their act together and does not care about quality customer service.

If we had another service provider available to us, we would jump on it and say good riddance to Comcast!!!
