Do not waste your money on the new Opel Mokka, car blocks my ears link I am in an airplane everytime I drive it

I bought a new Opel Mokka in November 2023 at William Hunt Fourways and within 3 days I could hear up whistling coming from both sides of driver and passenger and wind pressure blocking my ear. They took the car to fix and the noise was worse when they brought it back. The sales manager said it needs a technician and will only be back in January 2024. December 2023 they took the car again and only brought it back 06 February, the wind noise can only be heard at 110km p/h and now the car blocks my ears like I was is the airplane every time I drive fast. I reported it and they claim they did not hear anything the car is fixed. We scheduled a test driver together with the sales manager and service guy, the test drive went terrible, the services guy was busy talking about how his ears get block every time he is driving in any car he drives and the sales manager even went as far as saying what is the problem is and not car since he does not hear anything what are they going to fix. this is my fourth new car I am only experiencing this with this car. Do not waste your money on this car. I am taking them to the ombudsman, I am going to appoint a car expert to assess the car and give a report that I will use in court when I sue them for damages.
