Bajaj Auto — Non Receipt of RC after More Than three months of purchase

I have purchased Pulsar 125 from Global Bajaj Ganesh Nagar Delhi on 25 October 2021 but not received Registration Certificate till date.I called up a number of time but call was not picked up and no response received from Bajaj Global staff. I felt like no need to respond to customer after sale of vehicle. Also i don't receive d any receipt of breakdown of amount paid at the time of purchase of vehicle as it was informed that the same will be given along with RC. Such response was not expected from such a reputated auto company. Kindly look into it.

Regards
