By 2015, Absa clients were able to personally reverse unauthorised debit orders at any time by logging on to Absa internet banking.
Absa does not charge for disputes made online and reverses any charges levied against their clients if their investigations reveal the client did not authorise a debit order.
Kuben Chetty, head of the transactional, savings and investment products for personal and business banking at Standard Bank, said they do not charge customers to dispute and stop unauthorised debit orders if they do so within 40 days. This is irrespective of the amount of the debit order and the channel used to dispute and stop the unauthorised debit order, he said.
Chetty said they only charge a customer R290 if a dispute is raised after 40 days.
"If it turns out that there is not a valid mandate in place, the fee will be not be charged."
Standard Bank clients were also expected to go to their branches to cancel or reverse the disputed debit orders.
FNB was recently reported as saying it had waived its fee for stopping unauthorised debit orders of less than R200. It did so to clamp down on this practice and to empower its clients, said Ryan Prozesky, the chief executive of FNB consumer core banking.
All four banks said it was the customer's duty to check their bank statements for any unauthorised debit orders and to report it.
Those found to be processing illegal debit orders would have their services terminated by the banks after their conduct was reported to the Payments Association of SA.
