In authorized deductions

I have been an ABSA customer for many year. The last few month I have been struggling with not authorized debit orders from my account. This force me to try and phone ABSA to reverse or contacting the bank or my banker or go and stand in a row. All of this takes any thing from 1 to 2 hours to over turn the transactions. Every time I aske ABSA to stop any NAEDO transaction for the future. The answer is that they can only stop the reference number and only for 3 months. The top is that I have to pay a fee to over turn the non authorized transaction. The story I am getting and every time is that it has been send for investigation or that new protocols are in place we’re i can stop these transaction before it happen. This weekend I try to do this but I am told it is running on a cycle and it can only be done after deduction. Question: ABSA knows about this and also the amounts and the description. Why need to investigated. Stop them! Why must I pay for the bank that knows about these people and not doing anything. Question. Do I stop my ABSA account as other bank are willing to help
