Bajaj Auto — Battery fault in bajaj avenger within 3 months of purchasing

I bought avenger 160cc on 24July 2022 from TCS Bajaj(Faridabad) and battery(Exide) stopped working by Oct 2022. Visited service centre Guru Nanak Bajaj in Okhla, New Delhi and they want to keep the bike with them for 4-10 days to get the battery repaired/replaced. My concern is why should I leave a new bike with service centre for these many days that too just for battery issue and who will bear my transport cost for these many days as I work in market and have only this bike as mode of commute.
