RTO India — Delay in correction of engine and chassis no

Address: Rto janjgir dist janjgir champa

I have submitted a request for correction of engine and chassis no which was wrongly done by TVS showroom..It's very disappointed tha it's been above 6 month but I have not received any kind of response from rto..I have requested the rto janjgir and rto Raipur for the same so many times.but the response is same.. kindly look into the matter and resolve the issue as soon as possible so that I can claim a insurance amount which is due since last 7 months.
I have attached herewith some documents regarding the issue.
