Worse service at Kokstad Ford

I bought a Ford Ecospot at Kokstad in August 2019, in September 2019 made 400km and gear liver got stuck I returned to Kokstad and they didn't do anything I must come and collect it. In April 2020 at 29000km got stucked at the middle of the road (engine not turning on) and I also returned to them. I didn't not receive a response for 3 days and I had to call them to find out and they said it had battery problem. Now it is at 41000km and has sound on the gearbox and they towed it on the 22 November but I never received any response from them, I had to phone them and said they are going to return my call but never phoned me back. I'm stuck and I don't know what to do please help.
