Empty promises

Last month I had an authorized debit go off my account (don't know this company), I was promised a call back by an agent the next day which was the 1st of September and that this wont go off anymore but the same amount just went off my account again. I honestly don't feel like my money is safe with FNB

I have previously told them that I only have one debit that goes off my account and they shouldn't allow any other debit but this is still happening...
