Early debit order - Bank Charges incurred

I have a debit order set for the 26/07/2022. Then MBD decides to try and debit on the 22/07/2022, 4 days before my specified date. (what is the point of Debi-check if everyone can just do what they want). Now I have to pay R150.00 in admin charges for unsuccessful collection. Then I call MBD and get sent from one useless person to the next. I had to call 3 different numbers to come back to the initial number I called. Pure incompetence. Who are training these people. I want my R150.00 refunded as this was not my error.
