Hero Motocorp — I'm complaining about engine stopping problem of Hero Glamour BS6

I have purchased Hero Glamour BS6 on 12.11.20 from Bhagwati Hero, Chirkunda, Dhanbad, Jharkhand-828202. Since beginning the bike has got engine stopping problem. Day by day it increased and presently it gives huge trouble. Whenever I apply clutch in front of a turn or bumper the engine stops, self start also not working properly at that time. Again every morning starting of engine is a big issue.I have attended first three service in time at the Chirkunda showroom but they could not solve the issue till date. The problem increasing daily and I can hardly ride the bike in crowded place. The problem need to identified and resolved quickly so that I can ride the bike safely.
