RTO India — issue of noc for car

Address:

New Delhi, Delhi, 411014

My daughter has a diesel car regn no dl9cg7546 of 2004 model. She gave me the car for my personal use. I am settled in maharashtra. When i applied for noc with all required documents at delhi rto in dec. 2016 the same was not accepted stating that it is very old car & as per the directives from higher ups noc can not be issued. Moreover the files of the old cars have been removed. Since taxes for 15 years have been paid as one time tax i fail to understand how can it be denied? Moreover no such notices have been issued nor has come in the media.
I want to know how can we proceed in the matter & whom should we contact to get the noc. If it can not be given will the govt. Refund the tax & buy the car at market value of such car. The car is well maintained, its puc results are good, not run for high kms.
Please help.
