Unauthorized debit orders are costing me a lot of money

For the past two years I have wasted time, energy and money going to Absa branches to reverse ******* debit orders. The most frustrating part is that on top of wasting my time and money (petrol used) ABSA still charges me a dispute fee for reversing these unauthorized debit orders. I also do not understand why all the debit orders that I have authorized to go off my account, show on my online banking. You are actually taking ~R40-00 (R9-00 Transaction cost and R30-00 reversal fee) for each unauthorized debit order that I have to reverse. To think that in some months I have to reverse about three, this is a waste of my hard earned cash. I am really frustrated.
