[Resolved]  Elica — Cook top issue neither resolved nor getting any help from customer service

I purchased a cooktop with chimney from Elica in hyderabad in the month of November 2020. After installation we started facing issues with the cook up forming rust and all the stands bent in a way it's hard to place vessels on the cook top for cooking. Raised a complaint with Elica on december 4th 2020 and haven't had any response from them other than case getting closed without any information provided.
