JD Power & Associates needs to have a class action against them for how much time they waste and data they collect before screening out surveyors

They have taken me 90% through surveys on many, many occasions just to randomly screen me out after pretty much every question has been answered. Has anyone else had a similar experience? I can't find anywhere in their legalese that they're allowed to drop you upon acceptance if there's no valid reason. I'm calling bullshit on this.
