Very unhappy with Chase. I had a card with a sizeable limit. I never charged over 30% of the limit. Was never late. Always paid well above the minimum payment (sometimes multiple payments in the month) and one day with no warning my account was closed. Called and they refused to give me any reason other than "we closed you." Never received any letter or email even saying I was closed. Very poor customer relations. I had the card making a couple auto payments so it really messed me up.
