After sales service @ Autohaus Centurion

Recently bought a car, was my first car with Autohaus Centurion, car was delivered with 3 wheel caps and Close to empty fuel tank. When I asked the consultant who was delivering the car about the Caps he told me that he would courier them, about the fuel he said I should fill up the car then send him the invoice, it's been 2 months now I haven't received neither, when I complained I was told to go buy the caps then send the dealership the invoice (though I was told they gonna be couriered), when I asked about the fuel I was told that they could only fill it up when "you in Pretoria pop by and we would fill it up" the lady said. Overall I'm not happy about the aftersales because now they don't care and they don't answer emails timeously but when I wanted the car they were calling and emailing...
