RTO India — dual registration of vehicle

This is regarding dual registration case of vehicle # hr55 t 6855

We have purchased new vehicle in year 2014 and registered in gurgaon rto.in month of april' 2019 at the time of renewal of national permit, we understood that the same vehicle is registered in gaya (Bihar) rto.
Due to this all online renewals are held up.
Online proof attached for dual registration.

We have contacted gurgaon rto and as per them first we have delete records from gaya rto.

We sent our driver and contacted to gaya rto, then their dto office. As per them, they will not delete any record, without letter / request from gurgaon rto stating "gurgaon rto has not issued any noc for this vehicle."

Gurgaon rto issued that letter, attached for your information. Submitted through whatsapp to gaya dto assistant (Ph. No. [protected])

Gaya dto submitted case to patna dto, but no solution till date.
On telephone we are getting reply : the work is under process... This is software issue... Nic will take care...
