This Company Ripped Me Off

Firstly, I bought a Renault Clio 3 2011 model and had it delivered to me in East London. The condition of this vehicle was unsatisfactory as it had scratches but the biggest problem I had is within that first week, the salesman contacted me and told me it was not actually a 2011 but 2010 and the financing company needs me to sign for it. I returned the car and requested the dealership to cancel the deal and refund me the deposit I had placed(R50000). This dealership refused and told me if they cancel then I will forfeit my deposit. They forced me to exchange for another car. I then saw this Citroen on their website at a price of R119 900. When I contacted this dealership, they told me the vehicle costs R149 900 and that the price on the advert was incorrect. The salesman convinced me that he can get the owner of the dealership to sell it to me for R129 900 because the Renault was also R129 900. Upon delivery, the vehicle was a direct opposite to what I expected. It had warning lights popping up and a rattling noise from the engine. The dealership gave me such a run around about it. I took it to a local Citroen dealership and a diagnosis was made picking up a number of problems cost
