Maruti Suzuki India — Replace the chassis of my accidental wagon r

Address:

New Delhi, Delhi, 110070

I got Wagon R, DL 3 CAD 7126 repaired from Competent motors mauruali in May, 2014 for a accidental repair. I have sold car now and during the car inspection it was realized that the chassis no has welded and it now cannot be transferred. The Authorities have advised me to me to scrap this car and its a big loss for me. I will file a legal case against competent on how they can weld the chassis no without my knowledge
