This one is pretty self-explanatory, but oh-so helpful: Customer Service Scoreboard gives you the overall score of some of the most used customer service lines around to see how they stack up. For example, if I would have checked this site before I called AT&T to complain about service interruptions last week, I would have been prepared for their less-than-stellar customer service — they have 29 negative comments and only 7 positive, leaving them with a total score of 48.31 out of 200. Come on AT&T — you can do better!
Since this is a crowd-powered site, you gotta put in your positive and negative comments just like you would if you were Yelping a restaurant. So don't just sit back and read the site, let's get to work!
