Unexplained Fees

I got charged an NRB accounting fee for a service i didn't subscribe for. when i ask the call center what it's about, i was told it's for business accounts and helps you setup budgets. when i told them i didn't apply for the service and i want it to be reversed, i was told the fee cannot be reversed. why is nedbank trying to make a quick buck by charging fees on accounts that were not requested. i have asked other people and they all have had similar fee charged. they say it can't be reversed because it's a system generated fee. but the system fee is collected into an account that can be reversed. i want my money back. i didn't open the account so nedbank can go around activating fees for services we don't need.
