This is when you vote with your wallet. Get a card at another bank or better yet a credit union. Commercial, for profit banks are usury.

I would say leave the card open, get paper billing (if free), and charge once a year just to have them service the account. But then, they could report that as part of their numbers and people might keep investing with them. Just stop doing business with them and if enough people follow then they'll go out of business eventually. Bad businesses that don't treat their customers right should go out of business....not be bailed out.
