VW Booysens sells S**** as cars

I purchased a second hand broken VW Tiguan at VW Booysens on the 29 DEC 2022 from windows making a noise when you close the doors to headlights leaking water and steaming up when the car is exposed to rain or if the car just go to the car was under a hose pipe something i enquired about and was told its my problem they cannot fix it I am sure they knew that they selling me **** To top it all off the car still have a service left that needs to be done on the 150k and this service is to be covered by VW today I called to book my car in to be services and was told that my service planned expired and i need to pay for the service to my surprise last year when they did a service on my car they never told me that the service expires they we aware that i don't drive the car much and that was what I did bring the their attention with the last service they told me that I don't have to worry i just need to bring my car in for the service when it is due Today everything changed I don't have any signed documents to say that my plan will expired the same lady who sold me this piece of **** was the sales lady at VW Booysens Charishka Opperman she wants to tell me that i was supposed to be called by VW South Africa who was supposed to inform me my plan will expire close to the expiry date which never happened I am already sitting with a car that is giving me so much problems and now to make matters worst they tell you that the car must reach mileage of 150 to be services and now that the car is due for a service they can comfortably tell me that it expired just like that I accepted that i was sold ha s**** now i still need to pay for a service that was due to me when i reached the mileage of 150k why was i never informed of the service that expired why must they inform me the day my car must go for the service why did they never listen to all my complains a few months after i purchased this s**** regarding all the problems its giving me why was it never looked into i am so disgusted with this service and i promise i am not leaving it here this is where i will use social media to raise my voice to warn people of VW Booysens and what they sell to customers what was i supposed to do if i dont use this s**** car daily to reach the mileage of 150k for the service to be done before it expires why was i not informed and if my car still didnt reach 150k Sept 2024 how was they going to service it why was i not called by VW South Africa as Charishka Opperman insist why did she not inform me when she sold me this s**** that services expire that shifting this blame from one person to the next nobody wants to take responsibility for the mess I please need answers
