How can I give props to Comcast?

I’ve just gotten off the phone with Comcast (internet/tv/phone company, for those of you who are not familiar), and they acknowledged that one of their associates had given me incorrect billing information. They then agreed to honor the original agreement I had made with this associate, taking a sizable monetary hit. There was absolutely no talk about my having to pay more. I’m floored – have never been treated so well by a large faceless company like this.

How do I tell the world that Comcast rocks? Other than by posting this question, that is. I’m curious after reading pdworkin’s recent question about Verizon. I tried going to consumerist.com, but they’re only a negative-feedback site.

Edit – I also tried on Comcast’s website, but don’t see an option for customer feedback.
