I worked for a company that used A/B testing to justify call-to-cancel; makes me angry every time I think about it. I guess that's one of the tricky things about A/B testing - it is easy to measure that call-to-cancel decreases customer churn, not so easy to measure the number of people that will never sign up for your service or the number of customers that do churn and swear to never use you again.
