Can creditors empty my bank account or freeze it?

Just got off the phone with a creditor. I owe capitol one 1100 dollars I was seconds away from settling the account. And now they know I have a bank account with wells Fargo. I didn't give them any other info I decided to just hold off on paying them today till I see my check Friday. Now I'm wondering did I make a mistake telling them where I bank? Will they freeze my account?
