I just closed a Chase credit card, and the experience couldn't have been more pleasant. A native-English speaker, answering the phone in the USA (pretty obvious), he was courteous, professional, and helpful. He made a retention offer (which I thanked him for and declined), he gave me the info I needed (how many points I had in my account and the points expiration date, reminded me to stop any recurring payments charging to the card, shred the card, etc.), waived/refunded the annual fee that was about to come due, thanked me for my business, no pressure, no hassles, no wasted time. I couldn't have asked for a better experience.

Chase is great, I highly value my long, positive relationship with them, and I will continue to be a very satisfied, loyal customer. I wish most of the other mega corporations I deal with had such good customer support.
