Utter disappointment from Standard Bank Car Finance

Since July 2025, I have been trying to get a settlement value to pay off a balloon payment for my dad's car. On various attempts, they finally advised the POA does not work and authorization letter is needed. This was sent and to date I have not heard back from Thobile Msimango. On the 29 Sept 25, having travelled to my dad in KZN, i was able to call and get the settlement and bank details to settle the car. On making payment the 29 Sept 25, the settlement of R92000 was still debited on the 4 Oct 25. On the call, the agent had not advised that this amount would be debited, but only the last installment of R4200. Now my aged dad is in a negative of -R85000, with no funds for food at the moment. It is currently an extreme hassle to assist my dad remotely to get the debit order reversed and the -negative bank charges to be reversed. My dad is not in a state to go to the bank to sort this out in KZN. This was really unnecessary of Standard bank to put us in this position without proper communication and especially since i made the settlement within time. We now sit with back an forth emails to the accounts department, wanting proof of the debit order they did even with the proof of payment being sent and the sms of the debit order they did.
