Inspectacar won’t refund my money

I bought a Toyota 86 from Inspectacar Gazina, and paid cash, on 12 April 2019. I live in the Cape so the car was shipped to Somerset West. It turned out to be a 2012 model, not 2013 as advertised and had numerous other defects. The only defect Mohammed, the salesman and manager, told me about was “trolly damage on the left door” the “trolly damage” was a 4cm gouge to bare metal. I rejected the car and sent it back. A month later Juan De Lange, after sales and quality control, promised me a full refund which would be in my account on 23 June. Still no payment on 5 May.
