Volkswagen India — Technical issue with the ac and gear box in polo gt tsi

Address:

560093

I bought POLO GT TSI 4 months back. Below are the list of issue i noticed in my brand new car.
- Steering wheel making noise
- Getting jerk in second geer
- outside dust and smell comes inside even when the internal air circulation is on.
- Headlamp allignment
I contacted whitefield showroom from where i bought the car. They gave me appointment after three weeks. They kept my car for two days to fix the issue. after servicing the car i still noticed that external dust and smell still coming inside and Jerk problem is still there. Whitefield showroom contacted me back for feedback. i informed the same to them. They again kept my vehicle for another two days and these problems still not fixed.
so i have left my car for 4 days and the issues still exist. Please let me know what is the next step. Its a brand new car and i will not accept these kind of service
