Webuycars.co.za False advertising

I bought a Vehicle/ Car at We buy cars at the DOME last Month. The Car was advertised as a Renault Megane III 1.2 GTline 2017 Model, both on the Website and on the floor at we Buy cars the Dome Branch. As per the advice of the sales person the vehicle was due for a 5-year Service and for warranty related problems, and I had to take to Vehicle to Service at Renault. At Renault I was informed that the Vehicle was NOT a 2017 Model, the vehicle was actually registered with Renault in 2015. We all know that the facts at play when one is buying a Vehicle are (Year Model, Mileage, Physical conditions, and Mechanical conditions) and I had considered these facts too, hence I had arrived at a decision to purchase the Vehicle in question. I write this complaint to express my disappointment and that We Buy Cars has falsely advertised the Vehicle in question both on their website and on the floor. The vehicle is NOT a 2017 Model as it was advertised and this could also speak to the PRICE of the vehicle. This false advertising and misleading information could have costed me in the feature especially when I have to claim with insurance. Since I head this information I drive this Vehicle with fear if anything can happen I stand to lose everything. I drive this Vehicle with disgust and less love which is the opposite of what I thought when I went to buy this Vehicle. I have been calling the webuycars customer care and the lady called Kimberly Mgomezulu who claim to be dealing with my case has been avoiding my calls and sometimes claiming that her supervisor in on leave of over a month now.
