Van Rensburg ignores clients after our "repaired" vehicle broke down completely

Sad to say, but now, 2 weeks after the Figo has been "repaired" by van Rensburgs's RMI workshop, the engine now makes a horrible noise, even louder than before the so called "repair" and oil and diesel are leaking from the engine. We tried to get hold of van Rensburg but he does not answer his phone, sms or whatsapps.
