Despicable Capital One Bank

Capital One closed my credit card today: "Principal owner(s) have past, present or pending legal action". Since I have been current on all payments, and since my legal status hasn't changed since I got the card, they have arbitrarily and capriciously breached our contract, denied me the equal protection of the laws, interfered with my actions in interstate commerce. Can't imagine a bank being run by despicable law breaking fools. Can you?
