Hyundai Motor India — car brake noise issue

Address:

Thane west, Thane, Maharashtra, 400615

I had given my car for last free service was asked to change the break pad and the car was used only for 16000 kms. I still went ahead and canged it by paying the cost for it, when my car was back from service everytime i applied brakes it was making a weird sound. After which i went to service center twice and both the times the car was kept for the entire day and i was informed that the issue was resolved but again i was facing the same issue

Finally when i went for the 4th time i was assigned a workshop manager after creating ruckus at the service center who informed me that he
Had identified the issue it was because of the brake discs he would clean it and and the issue would get resolved again i paid for the cleaning got it done
But the same issue was recurring. Then the workshop manager mr nadar informed me to that he would install the break boosters and the issue would be resolved that was done and still the same issue

Today i have given my car again at the service center mr nadar was not available so had to go through the painful process of explaining the same things again and leaving my car at the service center

Would request you to look into this as this mental as well as physical harrasment for a customer
