Maruti Suzuki — Not recieved Road Tax paid reciept .

Hi, I bought a Maruti Swift Vxi on 12/3/15 from Kalyani Motors, Mysore road. (KA 05 MR 2038) They didn't give me the Road tax paid receipt. Even after asking and even begging them, no reply form them. I even contacted their manager . yet the response so pale, that i curse myself for doing business with the, Utterly disappointed with the service.
