Results from another American Customer Satisfaction Index are in. Not too surprisingly, the 19 most hated companies include banks, airlines, Internet providers and AT&T. What was rather interesting was that Facebook, with it’s 500 million active users, ranked number 10. For a company that produces and offers nothing, that’s an impressive feat to be despised more than some banks and the Internet smeared AT&T. It pretty much required being an airline to be worse than Facebook in customer’s eyes.
