Hyundai Motor India — wrong manufacturing year in vehicle registration

Address: Chennai, Tamil Nadu

This is regarding my i20 hyundai car registration number tn21at0108
The registration details showing the year of manufacturing as 2013 where as the company records [came to know through service center] showing as 2011 which i came to know after buying the vehicle during car service.
This indicates i have bought it for a higher price which is actually not the cost of the vehicle.

I want the company to look in to this and give me a suitable solution as earliest.
