I bought a new bike on 23rd July 2020 from GSM Bajaj Khandsa Road Gurgaon.Whose registration number is HR26EJ0538 and registration date is 7th August 2020.Bike battery got damaged in February 2021.When I went to the service center, it was told that the battery of the bike will have to be left for 5-6 hours to charge again.
Even after that the bike's self was not correct.when again after lockdown I went to the service center for the third servicing of the bike he was told bettery is fully damaged.I was told that when the battery comes, I will put the new battery.Battery warranty is a year and a half.After that regularly he was told that the battery has not come.I got the battery deposited at the nearest service center Mahalaxmi Bajaj for battery change.10 days later they rejected.Reason given that the battery is manufactured in January 2020. While I Bought in 22 July 2020.Now I keep going round the Service Center, I am unable to find any solution. Please help me.
