I recently read this article about a script bot that communicates with Comcast (most likely they're employing script bots of their own) to lower your monthly bill. And it works. Not only did the script drop my monthly bill by $15, but while it was running, the Chrome plugin provided a handful of simple games to play while the bot did its thing.
When you need to provide direct information (like the last four digits of your SS#, or a confirmation) you can interrupt the script, and allow it to resume. Comcast warned me that my discount is promotional - meaning that I'm putting a reminder on my calendar for mid-December 2017 to address it again. But apparently one can run the script at will. I've no idea what will happen if I run it again in a month, but so far, I'm looking at a savings of $180 for the year.
Note that the manufacturer of the plug-in is NOT taking a cut of the savings. And asks no info from you in this regard. The plug-in is free, and the savings are all yours. When you install, I believe you have to provide your name, address, phone number, and e-mail address all of which are required by Comcast when negotiating prices. During the bot-driven discussion, you have to intercede to provide your Comcast billing number, or the last four digits of your SS#.
