VAF debited on settled account - won't refund me

I traded in my car for a new one and the first debit order was set for Sep 25th. However on Aug 25th I was debited R4263.81 for the old car I no longer had. On enquiring with the bank and requesting a refund I was told that the account was not reflecting as settled and that I needed to get proof of payment from the dealership and submit it to the bank. I requested the POP (stating payment was made Aug 17th) and emailed it to a consultant on Aug 27th.

Sep 4th I went to a branch enquiring about this as I still hadn't been refunded only to find that the consultant I had email the POP to had logged a query on the wrong account and this was then rectified during that visit, over phone with VAF. I received service request SMS stating the issue was due Sep 30th. I called the call centre about 3 times during the month because I was worried that on the coming 25th I would be debited for 2 cars.

Sep 30th I receive another SMS staying my issue is in progress. On the upside I was only debited for the new car meaning they've resolved the issue on their side but have not seen a need to refund me.

I'm tired of calling the call centre and going through security questions, getting a different consultant each time, waiting for the always slow system to load so they can check on the request, only to be told I have to wait for back office to fix it as they can't. I want my damn money back!! It's been over a month already.
