Cars24 Services — RC transfer related complaint

I have purchased a waganor car
2008 model UP14 gaziabad number from cars 24, 11 days earlier. At the time of purchase I have given assurity
that for any document related
work you will not to go anywhere
it all be done from cars 24 side
and now I have been told to go to
600km away Sultanpur which is my
address in adhaar to verify from
RTO.
How can I travel 1200 km journey
for verification and I have already
mentioned it before purchasing
the car that I am not able to go
to Sultanpur from Delhi for any
paperwork.
No official are taking this query seriously all are just raising query over another query. I am not getting any final conclusion from cars24.
