Unauthorized debit orders

Good day,

My account has been debit by three different unauthorized people in a space of a week. Since Absa has a free online facility to reverse debit orders, I then went online to try to reverse those debit orders and couldn't find them on the list. I called Absa immediately and I was told that I'm gong to be charged for each debit order, then I couldn't understand because the facility is free online and I asked why they allow me to reverse the debit orders that I have authorized but they are unable to allow me to reverse those that are unauthorized. And I was told that my call will be escalated and until today I haven't receive any feedback.

I have been with Absa for 17years now and I think it's time I stop being loyal and move my account.
