This wouldn't be difficult. As long as a customer could prove beyond a resonable doubt that they have been mistreated. Keepign track of phone calls can be done by providing an itemised phone bill! And it wouldn't be too hard for someone to forward on all of their emails to a group.

Good idea, but it would take a group of people who don't mind smashing their head off of a brick wall fro hours on end all day everyday. I value my sanity too much (what's left of it afetr dealing with these cretins anyway)
