After some unsuccessful tries negotiating our bill with Comcast, I read this article: How to Lower your Comcast Bill Price
So I called Comcast and went through the menu to "discontinue service". The lady was very nice and my line was: "I'm retired and my wife wants to lower the bill. She heard of a good deal with ATT and wants me to try them." The rep probably knew it wasn't DW but it made me feel better playing the beaten down old retiree caught between Comcast and aggressive DW.
Anyway our new bill is now $31/month lower for 12 months (no contract if we want to discontinue) plus some new packages we weren't getting. Told DW about how Comcast is scared of her now and she really enjoyed that picture. She's actually a lamb.
