Where are Customer Service Rating Systems?

mugnyte asks: "There are various ways to watch single complaints congeal into a groundswell of 'market issue' (Badware add-ons, Sony root-kit, AOL un-install, etc) via blogs and google numbers, but I'm finding no sites that rate Customer Service on an ongoing basis. I'm looking for something like the home-service-industry Angie's List or perhaps Tom's Hardware guide, but on the topic of Customer Service. Is there anyone doing the hard work to gather and legitimately rate companies by their quality of service?"
