Oh Comcast, How I Loathe Thee

What a horrible wasted day!  Comcast was supposed to be here between 1 and 4 to install 2 cablecards for our TiVo.  4:30 arrived and no tech!  So I called, and told the girl that I could wait for a little bit (since I had to work till 5 anyway) and see if he arrived.   She was supposed to have someone call me back to let me know when he was going to be here.  5:15, I called back and they said that I was the next stop and that my newly scheduled appt was from 4-7, and then when I asked about the $20 credit that they advertise, the guy gave it to me.  Apparently you have to ask.  So I waited till I could wait no longer, since I had to drive across town to get Melissa. 6:15 I called them back to find out WTF, and of course after I get a rep on the phone I hear the guy knocking on the door.  That rep said she would give me another $20 credit.  Well, I let the guy in, and ran back to get the phone and tell the rep he was here, and I told the guy just to install the cards, and left him to his work for 2 min.  I assumed he installed them, since he showed them to me.  Then he goes on this tangent about how they have to do some BS, and I told him that I was walking out the door.  So he said he (or someone else) would come back tomorrow to finish it.  Well the idiot didn't even install the cards!  We have to pull the whole TV setup apart to put the box in, and wanted the cards installed, because it will be impossible to get them in once it's put in place.  What a bunch of BS!  I am so mad at them!!!!!!  Now I have to wait around to see if they are going to show tomorrow!
