Standard bank incorrect advice on product

I opened a savings account with standard bank in 2013 and was advised by a consultant that it was one of the best options they have for me. Months later I was called by one of their department informing me that my salary bracket was too high for this particular account and they then offered me a cheque account and transferred all my debit orders to the new account. I now received another call from the bank requesting over R700 in bank charges for the savings account I had instructed them to close due to their own incorrect advise. I refuse to pay those bank charges due to their staffs negligence. I want this to be resolved ASAP or I will dispute it with the FSB myself.
