Ford India — Incompetence of Harpreet ford Gurgaon

My old car that was exchanged has still not been registered in the new owners name. The guy has violated traffic rules in Delhi for which he is getting challaned the challan is being sent to me instead of the guy.
Harpreet ford had assured me last year that they had made sure the new owner wud register the car in his name
He hasn't done it in 5 years.
The general manager Pawan can't b bothered taking my call.
The police need to be told I have exchanged my old car for a ford EcoSport.
The old car is no longer in my name.
Should not be.
No one at Harpreet ford is taking responsibility.
I am harassed every year because of this.
Can someone look into the matter asap please???
