Months of painful failed debit orders and bank penalty due to standard bank insurance failing to change my debit order details

I have been nagging the insurance team to change my debit order details for month, fortunately earlier this month I launched a hello Peter requesting them to give my pain attention and the lady contacted me to confirm that they have been successfully changed and I took their yes, to my worst this was Infact changed to Standard Bank account when I made it clear that I want this to deduct from FNB account, this resulted in unpaid penalty fees unfortunately and the insurance team must account for such penalty as this is negligence and after commenting to my previous hello Peter Post nothing has been done until now.

It's like they are indirectly forcing me to use their standard bank account and I want nothing from them anything and they must close my transactional account too as they fail to honour what our relationship is based on
