Hero Motocorp — Bike off while running and self starting not working

Address:

Bike off while running
Self starting not working

Note: For my last bike service they forget to tight back wheel main bold.

It's very annoying.
I told this issue while bike service time and they said battery got affected so need replace the battery. Actually bike bought before 10 months only. So they re-claimed from battery vendor and replaced into my bike. But again 1 or 2 weeks again issue started. Myself and my family members hate the bike riding (Passion Pro). My brother's named the bike as failure model. It's very painful and it's our first new bike for my family. Kindly do the needful at earliest
