Hello Sir/Mam,

I have purchased a two wheeler with the registration No. DL3SEC6469 in Nov.2018. First time I received the RC but father's name & address was wrong on it. Then I ask the same to dealer from where I purchase my bike. He has send the RC for correction in end of Dec. 2018, but till now I am waiting for the RC.
I have still not received any text message regarding dispatching of RC. I have visited the RTO office Kalekhan but the people sitting there is not responding properly.

Requesting you to do the needful & help me to send the RC at my address.
