Lack of FNB ***** reaction and prevention

I have now notified the bank and disputed several incidents regarding ***** on my account.

Despite this, multiple debit orders are still going off, and when I called to have these reversed, It was said that the consultants which deal with the ***** via debit orders, do not work on Sundays.

Surely in today's world with internet ******** and electronic *****, the ***** hotline should be a priority to a bank? I am extremely disappointed in how this repeated incident is happening and how it is being handled by the bank.
