Misrepresentation of vehicle information to get it sold

I recently purchased an Audi q3 from Jhb south branch . I inspected the dekra report and noted the defects of the vehicle and all has been rectified and paid by me before taking delivery of the vehicle. After 2 weeks I took the vehicle to Audi for its service which was currently due and was informed by the technician that water is leaking from the right hand side headlight spray mechanism due to a previous accident damage on the vehicle. Which is causing a continuous beep and warning light on the dash board.

I am highly disappointed that we buy cars did not even mention it on the Dekra report and misrepresented the information about the vehicle just to get it sold. The dekra report did not even mention about panels being resprayed. Customers do not go on their knees to inspect every single detail when purchasing a vehicle hence we rely on the Dekra report which is provided when purchasing the vehicle.

I would like we buy cars to rectify and fix the vehicle or else I want my full refund on the vehicle!!
