Pathetic service and a car that's sitting at bidvest Nissan Randburg since November 2023

We sent our Nissan NV200 in for repairs in November 2023 at Randburg Nissan on Malibongwe cnr Avon. They still have the vehicle and they still have no idea how to fix it. They don't answer their phones. Lindsay was utterly hopeless. Empty promises about calling back but never did. Then Werner the manager was even worse. He made all the promises to have that car sorted out. It was always next week, next week, next week, but it never happened. Eventually he stopped communicating too. We don't know what to do anymore. We just want our van sorted out. How is it possible that Nissan cannot fix their own product? And if they cannot, then surely they must just give us our vehicle back. We have lost so much business because that vehicle has not been on the road.
