Refund Flawless Cars Selby and Cape Town

I bought a Hyundai I20 from Flawless Cars Selby in Johannesburg on 20 June 2025. I over paid by R5000.00 and I was informed that the refund will be processed the following week in June 2025. We are already in July, almost a month after the payment and I still have not received my refund. I had to keep calling the office and the salesperson Lisa and there is sometimes no answer or no communication. I ended up going back to their offices and I was told that I needed to complete some refund form from head office in Cape Town. The forms finally arrived on the 4th of July and I returned the completed forms with supporting documents on the same day. I was then informed that the refund will be paid within 7-10 working days. Guess where we are now and still no refund. I have been calling almost every other day and no feedback even on emails. There is no contact number for the Cape Town Office anywhere even on the refund mail, so how the hell am I supposed to follow-up. I have called Lisa in Selby today and she said she will send the Cape Town number now but I still have not received it. I am overly annoyed at the unprofessionalism and treatment. I want my refund and cannot wait any longer.
