Unfair Customer Treatment

Hi All, Bought a 2017 Eco Sport from Mcdulling VW in Booysens This was in 2021 August.3 days later noticed that the car is not painted nicely and has different shades of grey,The windscreen had a crack,side skirts on the car were scratched car had an oil leak eco sport signage is on the wrong side of the car not like all the other cars.The car engine shakes when the car starts.I reported all the above the same month in 2021.The sales person booked the car in on a Saturday and only the windscreen was replaced in 2021 I was given runarounds about the other issues I however kept communicating with the sales person and was told the manager is looking into the matter.A year later the oil leak was getting worse I contacted the sales person again and told him I had enough now and was on the verge of seeking legal assistance following which he then confirmed I can bring the car in and they will sort out the oil leak this is August 2022 .However when the car was booked in I was told top management is now singing a different tune these where the sales person exact words.He told me he does not understand why now his management is changing the tune by refusing to fix the car as according to them the car warranty has expired since its a year later,He further advised that the matter was bigger than him now and I would have to liaise with the Sales Manager Andre.I went to Booysens on the 30th August 2022 in the morning after the car booked in on the 26 August 2022,I was frustrated as my wife is using the car and was without a car and had issues to go to work.I met Andre and explained to him that I have been communicating with the sales person for a year now and that I dont understand why I am being treated like this.He said he will try assist me but I should pay half the money which I refused and he later told me the car will be fixed and I should look at getting a warranty.My query is that the paint job is still not done and I am still dissatisfied as a customer The car is 280,000 I was never told about the car being resprayed I only know that the car is a used car which I am more than happy to pay for till the end for as long as the car is painted properly The last email communication between my self and Andre the sales manager was that he was going to escalate my concern to his manager and would revert to me on Monday 12/09/2022 I haven't heard anything from him till now Please help
