I purchased a prestige pressure cooker 3 years back and recently a hole created at middle of the outer lid during cooking. And i visited the prestige regional service center, Cuttack but unfortunately they refuse to repair/replace the product mentioning that this is due to misuse of products and also mentioning that they only replace product free of cost only if the manufacturing defects arises within 2-3 months of purchase.
If they replace product free of cost within 2-3 months of purchase then why the company mentioned 5 year warranty on this product.
In the term of misuse they are playing with the customer because my product has no physical damage and has no clue that this hole is made physically even i can prove it.

But unfortunately they unable say what type of misuse, how it is misuse.
