Mahindra And Mahindra — zero service result from koncept mahindra

Address:

okhla industrial area, New Delhi, Delhi

Last year in march me with my car xuv 500 met with an accident in which acc to me whole front was approx damaged. I got it repaired in koncept mahindra okhla industrial area for which they raised a bill of approx 4.25 lac which was covered under insurance.
Right after that i continuously faced problems in the car which initially i got it sent and repaired in their service centre but getting frustrated since 10-11 months and after knowing that my gear box needs to be replaced for the 3rd time, i finally decided to sale the car.
Now when i enquired for selling my car, everyone told me that you cant sell your car bcoz your chassis number is not clearly visible. I was shocked bcoz i never thought about this.
Now i am in a position where if i drive the car, i need to incurr charges everyday and if i want to sell, i am not able to sell my 4.5 year old xuv 500.
