Car sold to me was not the car advertised!!

I bought a vehicle through we buy cars in September 2023. Vehicle was advertised and sold to me as a high performance 2.0L 165kw vehicle. Traded my other vehicle in and had to load an extra R29000 to the new vehicle due to the settlement shortfall but I was happy with the deal. Took the vehicle in for a repair in March 2024 and was informed that the vehicle was not the high performance version I was sold and paid for. It was a small engine less powered version. I contacted Webuycars and requested a refund for the difference in value which was around R40000. The branch manager at Brackengate said the cost difference is R2000. From a high spec vehicle to the entry level vehicle?

Firstly, I was *****ulently sold a vehicle which was not advertised and the contract and bank finance refers to the incorrect vehicle. Now I am told I can cancel the deal but I have added expenses which I incurred during the purchase. I traded my previous vehicle and agreed to the loading based on the vehicle purchased. Will webuycars settle the remainder of the loaded amount on the vehicle based on the R28330 I already paid on the vehicle installment as well as reimburse the money spent on a warranty I was forced to pay for and the on the road and licensing costs I was forced to pay. Purchasing this vehicle from webuycars has put me in a predicament where I now may not be able to purchase another vehicle because of false advertising and webuycars selling me the incorrect vehicle. This is the 7th vehicle i have financed and it is honestly the worst experience I have ever had purchasing a vehicle. I spent the entire day at webuycars when purchasing the vehicle to ensure I got the vehicle I wanted and had to jump through hoops to get it and now to have this happen. How does a company like yours sell the incorrect vehicle? Do you not check the Vin numbers and verify the information before advertising and selling the vehicle?
