NRB accounting subscription fee

My account has been debited for an amount of R 225 since December last year for an NRB accounting subscription fee which i apparently sighed up for on my online internet banking ,I have went to the branch and they could not assist me,i was told to phone the call center where no one knew what that was for,eventually i got a number from a lady which only rang.this is rather frustrating as i am on maternity leave and i cannot afford these extra debits neither can i leave my baby and keep going to the bank.i have lost R 1 575.00 which i failed to retrieve from my bank.Why can no one assist in stopping this debit order and why do i have to phone any one else but MY BANK.this is my account which i have no control over and i have no assistance from nedbank.
