Bad service from First National Bank

I have a problem with FNB. I want to move my account there to them but was informed that i had fees from over 4 years back. Almost R3000 that i have to pay before i can get a bank account there. That to me is unfair because where must i get the money to do that and is that their way of showing clients away. The consultant told me yesterday to open a savings account that i can use to pay back the outstanding fees on a monthly basis.
