Yes, but like a credit card debt, the bank doesn't care about your debt so long as you make minimum payments each month. You're engaged in the system and they are benefitting from your continued custom.
But if you decide you don't want the card any more, they will want that paid off in full immediately. If you refuse to pay then you default and the only way you'll ever get credit from anyone ever again is by paying a ridiculous rate of interest.
And, no, going to the bank and claiming greatness isn't going to change that, nor is saying "you need me to use your services in a way that harms your business more than I need you to supply me those services." Because that's not how banks/trade deals work.
You clearly don't know how credit cards work. You can cancel a credit card at any time and still pay it off monthly as long as you make the minimum payments.
