Hyundai Motor India — regarding sales invoice

I was a proud second owner of hyundai i10 till recently which was sold out for my new car. Initially i preferred exchange offer in which the showroom asked sales invoice of the car. I went to the showroom where the car was purchased 9 years ago for sales invoice. My request was not accepted as in their book of records first owner is the person to ask for, but i legally transferred the car to my name, but they are not accepting that. To them i am a third party. The response i got was to bring letter from first owner whom i am not sure where he will be three years after i purchase the car from him. Whether he changed his address/whether is he is alive etc. But to my luck i got it sold to another friend before this situation could be solved.

I humbly request the concerned authorities to look into these type of matters and do the needful so that any other customer like me does not face problems
