Hero Electric — Under warranty battery is not replacing

Address:

Najafgarh

I purchased Hero Flach scotty on[protected] from Yuvaan automobile and now my battery is not working. I have checked from Yuvan automobile Najafgarh and he is saying it will not be replaced under warranty when battery charger already replaced in Dec-2021 and battery is not replacing because it more amounts compare to battery charger.
Note-please replace my battery in it is under warranty.
