Rto India — rto noc update in vahan

Hi team,

I transferred my vehicle from bangalore to rajasthan (Udaipur) and obtained noc from the rto on 26 june 2018. For re-registering my vehicle in udaipur, the rto is asking for vahan site updation, which hasn't been done by bangalore rto. Tried reaching bangalore rto, but, the response i get is that the site updation is not taken care by them. Please help me in getting updated noc status on my vehicle - ka51mh6736. It has been 4 months since i have been trying to contact rto and vahan, no one is taking responsibility to get this fixed.

Thanks,
Ali
