Maruti Suzuki India — manufacturing defect/quality/service

Address:

560068

My vehicle number bearing registration number ka05mw3826 which was delivered on 24/10/2017 by nexa dealer jayanagar, bangalore. The issue started with the brake noise when the vehicle reached 250kms. The service guy's informed it's due to the dust, rain and so on. It's a whistle like sound comes while applying brakes and also on reverse. The vehicle was taken to workshops 4-5 times and the issue is not solved.
This is highly dissatisfaction to the customer who has paid 10lakh to the car.
I am shocked that the techinicians are not able to rectify the issue and a poor quality of service. I am feeling like u people have cheated and delivered me a second hand vehicle by taking 10 lakhs rupees.
Worst vehicle ever seen.
I want this issue to be rectified with immediate effect.
