I have a buddy that works for a major credit card company... they have let some of their customers go... but not for a reason you expect (complaints, ect).
He said it was mostly older people... or folks with some kind of social issuse... and they just wanted somebody to talk to. So they would just call up customer service just and just rabmle on and on. The CS folks, for the most part are always friendly/polite...and they can’t exactly hang up on right away.
So these folks would just keep asking about balances, offers, rates, whatever... to keep the CS person on the phone.. just to hear another live person.
That’s kind of sad.
