There are currently two law firms suing KNC on behalf of customers. One is going as group lawsuit, and other is going individual. There is Pro and Cons for both, and about 80 people have filed against them. I am not sure if any new cases are taken by them (might be possible if you go solo), since both law firms have submitted their case to court and awaiting court hearing date. If they are able to get court decide all customers are consumers not businesses. It will be over soon. KnC would appeal but they can't appeal for next 10 years or so.
