You kept on using an ATM card without having a clue as to what your balance is! Please tell all of us how smart that is!
NSF charges are a big profit center in banking because they know far too many people won't keep a written record of their account usage...JUST LIKE YOU...they keep using the card, running up overdraft fees and then blame the big bad bank...JUST LIKE YOU.
Banks should increase NSF/OD fees to minimum $100 a pop. Why not make a profit off of people who don't use common sense!
