I'm in Hoffman Estates, so I assume we both are serviced out of the same office (Rolling Meadows). About 1 month ago, I called to get the ball rolling. Based upon comments here, I decided to call the 1-800-comcast number instead of the "local" number supplied on my bill. I said I want to order cardcables and assumed I would be transferred to "a specialist". I was not but the guy did not seem to have any problems when I mentioned Tivo Series 3 and two cablecards. He scheduled an appointment and we were done. I did not talk to him about costs.... I figured it is what it is..... On the appointed day, the tech arrives. He says he has done one Series 3 before. I tell him I have been reading other user comments and it seems the instructions need to be followed exactly for success. He is a mellow guy and does not object. He was issued only two cablecards... he says the company does not allow them to check out extras to carry with them. I had previously set up the S3 for basic stuff and made sure it worked, got live TV, etc. He inserted the first CC and it would not work. Error message that made it obvious it would not work. He removed it and tried the second one. This one worked and he called it in and got that one working. He called the office and had someone grab another CC and drive over here. That second one worked and I was all set. The install time was 1.5 hours but it was almost all wait time.... him on hold when calling his office and the delivery of the replacement card. I got my bill after the install (about 3 weeks) and it shows a credit for two returned set-top-boxes but NO charges for an install OR cablecards. It appears this was all free for me. I have the platinum package which is all premium content and Internet. If I were to do anything different, I would try to get the initial order to indicate bringing an extra CC just in case as the install failure rate seems to be very high.
