FNB doing whatever they want.

I'm on a package deal. When I changed my bank to FNB I signed on with the specific contractual terms. All of a sudden for the last two months my debit orders are charged. R70 here, R10 there.... Phoned in and was told it is the "new fee structure". It is completely ********* in my opinion to just load new fees when and Where FNB feels like it. I can understand escalation in fees, but loading on new fees, that may amount to hundreds of rands per month, completely unilaterally, is borderline theft.
