Tech Mahindra — mahindra kuv

This is the condition of my car in just 5 months. Roof of my car is damaged by rust. There have been other problems as well.
1. Parking censor is not working.
2. Fog light doesnt work either.
3. Seat covers doesnt fit properly.
These two were included in the kit that i purchased for 70k. I took my car to mahindra showroom located in noida sec 2. Their behaviour was very unsatisfactory and rude and they sent me to their body shop centre in sec 60, noida which is 20 kms far from my place. I am very disappointed with their customer service and quality of the paint job on the car. I would not recommend anyone to ever purcase a mahindra product.
