Elica — Elica Hob & Chimney Worse after sale service

Address:

www.elicaindia.com

I've bought Elica Hobb & Chimney last year with no service given during warranty period. And today some agent called and said that i need to pay for further warranty period.
I've raised a complaint for usual service after 6month of buying the product but no one turned up. And we understand that may be due to Jan'2022 COVID wave they must have not come. But even after thing went normal no one turned up. And without my knowledge they closed the complaint as well. I request Elica India to look into this issue.

Worst after sale service experience ever. :(
