Inefficient Service from Wesbank

I was required to refinance the balloon payment on my vehicle. I contacted Audi Financial Services a subsidiary of Wesbank and a individual by the name of Refiloe Matjila assisted me. The refinancing was finalised on the 05 Nov 2021 and I was informed by this person that there would be no debit order for Nov as she had consolidated this into the refinancing. However, I still get statements indicating that I owe the balloon payment and my account was debited. I have emailed querying and get no response, yet they will be quick to hand me over due to incompetence. This is terrible service and I will never consider Audi Financial Service in the near future.
