Pigeon Appliances / Stovekraft — Replacement of defected induction cooktop under warranty.

I had purchased two induction cooktop from flipkart model name Pigeon Favourite IC 1800 W Induction Cooktop. One piece got delivered on 25 September 2022 in Kerala Address which I ordered for me and Second piece got delivered on 06/10/2022 in UP address.which I ordered for my mother, both products were purchased in big billion days sale. Both pieces had some manufacturing defect as when I plugged the product a boom sound came and the product top cracked and is not functioning. Same issue happened when my mother plugged the product in UP. Same issue in both products at two different locations happened in the same way, it is a clear case of manufacturing defect. As the product has 1 year manufacturing defect warranty I want to claim the warranty against it in both the pieces but the worst part is the customer care number provided on the warranty card and pigeon site are not working which is a clear case of cheating. I want the replacement against the product.
Kindly help.
