Here's a copy of my email to comcast: To whom: I have been trying to get a M series cable that works for three weeks now. Yesterday I went to the local Comcast store and got the third (3) cable card. Called the activation line after work and all they could get on it was the basic channels. I dont want or want to pay for all the pay channels (HBO,Showtime etc) but I would like to get the ones I do pay for ex History, ESPN, USA etc. Since Im tired wasting my time and my gas going to the Comcast store every couple of days I have an appoint to the cable guy to come out this coming Sat. I asked that they put a note on his work order to bring a pocket full of cable cards so I dont have to make more appointments. Please look at the notes for my cable card history. It was first card said it was bad went and got the second card. On Friday evening we got that one going and I was so happy I didnt even check all the channels. Called back Sat when I saw I was only getting the basic group. The phone tech Sat got them going and they lasted a week till this past Sat. when they dropped out again. After another couple of hours on the phone I was told it was my account that was authorizing the right programming and they couldnt get them on the weekend to fix it. Then on Monday we tried again and still only basic. Said it was another bad card. As stated at the top of this email what happened yesterday. This isnt new tech, your Comcast boxes (the HD DVR ones any way) use the same cards for the signal decoding. I dont understand why someone cant get this to work. I know its not on my end because the one guys got it going fine for a week or so. Please have someone follow up on this because its getting absurd at this point. And tell billing I would like a rebate on a week of service to basic because thats all Im getting.
