Hero Electric — Scooty broke down from Chassis

Dear Sir
I purchased a Hero Electric Optima LX on 12th March, 2021. But due to the poor quality and manufacturing defects my scooty had broken from the chassis while I was driving which could have led me in a serious accident or injury. There is a crack in the chassis. I am deeply shocked to see this from one of the renowned two wheeler brands. I took the scooty to the concerned automobile dealer and he refused to change the scooty. Everyone wants to now switch to electric and if this issue comes under limelight then no one will prefer the electric two wheeler. Kindly improve the quality and the equipment.
So I request you to either provide me a new scooty or refund back my whole amount as soon as possible. I will be very thankful to you and wait for your reply at the earliest. I am attaching the details for your reference.
