I love my Keurig K-Cafe.  Unfortunately, the coffeemaker was not working properly.  I was hesitant about the run around I would get when calling customer service but boy, was I surprised! I explained what the coffee maker was doing and they said no problem we'll replace it.  The sent me the list of required information which I promptly sent and within 3 days I received a new coffee maker.  As my title says: this is the best customer service ever!
