Hyundai Motor India — Damaged my car

I have given the car for bumper replacement in that they have damaged my front panel above bumper plus right side fender damaged plus they have scratched my car .

For panel & fender fitting car went 4 times but again & again old issues coming and during first time they bended my car bonnet thru hands & bang with hammer also (recording available), later during 4th visit the workshop words were this "man labour fitting & machine fitting will totally be different & no one check like you ever" so my thing is if you can't provide proper stop calling it 'HYUNDAI AUTHORISED WORKSHOP"

I want my car to restore in showroom condition
