BMW India — Navnit Motors asking 250000

Address:

Mumbai City, Maharashtra, 400069

I own a bmw x1 it was parked at my building when I don't know how my sunroof rear side broke by itself ...I gave it to navnit service centre in andheri east ..they replaced the glass of 29000 in insurance m took 5 days to replace ..fair enough ...now on the 5th day the service centre guy calls me saying that sir your lock has been broken of the cardboard thing that closes n opens beneath the sunroof and that the whole assembly needs to be replaced and 250000 is the cost of the assemble n I wil have to bear half the cost ...when I gave the car everything was in perfect condition and they broke the lock while fitting the glass and now asking 250000 from me. ..I am really ashamed to have owned this car ...
