Citibank Bank Account Or Service Complaint

I have paid my Macy 's account balance - separate times, and yet I still see another $2.00 bill added to my account. I know I have paid the balance off so I do n't check since I have not charged anything at Macy 's. How do they get away with the practice of adding a $2.00 fee to my inactive account?
