Complaint Review: Charter One Bank

I initially became a Charter One customer because of the Totally Free Checking promotion and Boy have I learned that don't beleive everything that you read. I had been using my debit card quite a bit as usual but when calling the automated lines instead of getting an accurate balance I was getting an erronous balance, but what makes it worse I was using my DEBIT/ATM card for small purchases anywhere from $1.77 - $30.00 and they not only allowed one to go through but over 15 even though

they NOW tell me after the fact that my account was overdrawn, these debit card purchases were made overs days and not all on same day and it makes me upset that they refuse to credit the fee(s) even after I asked them to calculate the amount of items that were paid with insuffucient funds but they want these $33 fees which is in excess of $500,

please note I have never had a ONE returned check with them but now have learned that I am not alone. I have written to their BBB contact but she has never returned a call or responded my my fax or email. I am asking for any advise of suggestions on how I can remedy the situation as I dont mind accepting responsibility for what I bought but at the same time I didnt sign up for a credit account with them with the understanding of a $33 per fee per transaction. I have acted in good faith but I really am upset and don't want this to affect my credit.
I welcome and sugegstions
