Heart broken client

It really breaks my heart to write this. I bought a Nissan magnite but I have never enjoyed the feeling of owning it. When I first bought it a week later it had door knot issues. Second the window started acting up 3rd door rubbers started giving m issues and it fell off. 4th window is acting up again 5th the strip next to the window is now lifting on the other door. 6th I took my car for service Friday and the next day I got an error that says check anti pollution system. What is next? Why sell me a car that I can’t even enjoy. Nissan east rand mall knows all about my issues but no one has given me feedback on how we can solve all these issues. I bought my car from them so I need answers on why I was sold a faulty car
