Kropex India — Chevrolet beat diesel

Address:

560100

I am facing this major issue with my chevrolet beat car.
During rain lot of water was entering car. This water wont dry off. During regular servicing service adviser suggested that this is due to rusting door.
I am shocked to see quality of material provided by gm that door started rusting in 4th yr. I have taken extended warranty from gm.

I have done all servicing at gm authorized center kropex at hosur road banglore.

I have requested to gm and kropex to replace door as i have extended warranty.
But i am not getting any response back. I wrote multiple emails.
