Elica — Automatic cook top not working

Sir I have purchase whirlpool ( Owned by Elica) automatic gas cook top in March 2023 from Vijay sales Asharam road branch, Ahmedabad and very next week I started rasing complaints for it. So this real harassment for me as such each and every time executive come and make visit and says it will not happen next time.
I have vested lot many time for this complaints . As such soon after I purchase the complaints started so I ask company either to refund my money back or change cook top with the new one.
But nobody cares to do that.
