I also received a call from this number from someone claiming to be from Comcast.  He said that it showed I had cable and internet with Comcast and he had a promotion that could help save me money.  He said he had a few questions about my television viewing habits and asked me what kinds of things I watched on TV.  Currently, I don't have a TV and don't watch TV and told him that.  He responded with "Oh, I see, you don't have a TV.  I'm sorr--" and promptly hung up.  I called back to see what kind of scam this was and got a message saying that I have reached Comcast and to leave a number.
