Brand new vehicle with broken gearbox!

<p>HI there <br />I'm contacting you on behalf of my mom. She purchased a brand new Audi A3 S-Tronic at Audi Claremont. When she took delivery of the vehicle she noticed that the vehicle didn't "feel right". She immediately called the salesman who said she should drive the vehicle for another few days and see if the car feels the same. Eventually she took the vehicle into the workshop, where they replaced the gearbox. Firstly, they didn't authorize that with my mom and secondly the salesman said they would only take the vehicle back if they find the problem exists in 10 vehicles of that model. To date, the owner at Claremont is not budging at all, he wants her to take a brand new car and start her repayments all over again. No compensation at all , they basically want her to put herself into more debt when she has already paid about R150000 on her car. The car is financed through MFC and they are saying Audi Claremont needs to sort out the matter. She's lodged a complaint at the ombudsman but they have closed the case now. She is still not happy with the decision and she (being the customer) is worse off now. The current trade in value is R240000 since the gearbox has been replaced. This has been going on for a year now and the vehicle was originally purchased for R430000. </p> <p>Please help. This is not right. <br /><br /></p>
