Toyota — Non transfer of RC

Address:

Booty more, Ranchi

I have purchased used car from Heritage Toyota Ranchi in June, 2022 and he promised me to transfer Ownership but he didn't transfer ownership yet, I have told him so many time but they told me only paper is in progress,
From January, 2023 my vehicle fitness is also expired and I am unable to renewed vehicle fitness due to non transfer of ownership,
So please transfer my vehicle ownership as soon as.
