Refusal to repair defect on vehicle

I bought a car from Automania on 16 October 2014 and on the same day reported a fault on the vehicle. The dealer told me to get a quotation for repairs. After submitting the quotation, the dealer refused to pay for the repairs. I then registered a dispute with the Motor Industry Ombudsman of South Africa. On 20 April 2015 the MIOSA ruled in my favour as my request for the dealer to repair the vehicle is in line with the Consumer Protection Act of South Africa. Since then I have sent numerous emails to the management of Automania requesting approval to have the vehicle repaired at their cost but my emails are being ignored. It is now almost a month later and I still haven't received any feedback from Automania management.
