Hero Electric — Regarding replacement of e scooty battery

Address:

P. K. Sales gulabbari ladpura 324006

I have purchased hero electric e - scooter 8 months ago and now it's battery is not working it is of no use within 8 months.
We have asked for battery replacement on the service center but they are saying it will take 1 months to get new battery we waited for 1 month but still they are asking for more time and telling us to wait more making excuses like the factory of hero electric has got into fire.
Also the customer care service of hero is not proper. No one is there to pick calls.
No response on email also.
