Was sold a bramd new polo 1.2 tsi comfortline

I bought a new polo 1.2 tsi comfortline 66Kw. At ****ms the car started giving me problems with the aircon pump. They took the car and fixed the aircon pump. After that was fixed my aircon didnt work proper anymore. I went to see the dealership last week after i booked my car for a service for thursday they couldnt help me with a courtesy car as i needed transport for work related matters. I have a problem with the car raining in, r/f wheel making a noise, sunroof is rattling, car is raining in, wind coming into the car from both front doors when driving and my driver seat is making a noise. I am really disturbed that a brand new car can have all these problems in less than a year. Upon the first default on the car which was 3 days after i got the car, i requested that vw replace my which they refused to do. Up untill today i still want them to replace my car as its really giving me a lot of problems
