UNAUTHORISED DEBIT ORDERS

After inspection of my bank statements, I found that debit orders have been deducted from my account that has not been in any way, shape or form authorised by myself. As far as my knowledge goes I need to authorise any debit order that is deducted from my account. How can ABSA allow a random company to process debit orders. When I phoned the ***** hotline they said I should lodge a case at the SAPS against the people who initiated the debit order, but is Absa not supposed to protect me against ********** activity by at least confirming debit orders with me that has not been authorised. When I opened a cheque account I had to sign off on all the debit orders that were to be transferred, when I open any other account at any company and I want to settle the payments via debit order, I complete a form giving them permission to debit my account. How is this then possible? Also now I have to go the branch and ask for them to reverse the debit orders, but come next month the amount will again be deducted because Absa cannot stop the debit order. I am disgusted at the lack of security you give your customers.
