Nissan deliverying of defective car

I bought a brand new 2020 Nissan Qashqai car from Nissan Secunda early this year (March). Upon delivery of the car by the dealer I found 4 defects from the car during the delivery inspection. Defect no 1: Damaged right hand roof rubber rail Defect no 2: Damaged left hand roof rubber rail Defect no 3: Damage windscreen rubber Defect no 4: Wheel sound on the rear left wheel. I was promised by the dealer (Ann Botha) that these defects would be addressed and I can take delivery of the car. We then took pictures of the defects and the dealer was fully aware of my defects and seemed to want to address the issue. I took the delivery of the car and now it has been full 8 months and only one of the defects have been addressed (defect no 1). I have been very patient however I have lost patient now. I want these defects to be addressed. I am very disappointed with Nissan, I thought the brand was world class. But this experience have made me rethink being part of this brand. I'm very disappointed.
