I had purchased a four burner gas stove on 23rd June 2015 from paytm and on 23rd spetember 2015 when one of the nozzle was on, one of the other nozzles caught fire suddenly and the toggle melted. Not sure how safe is this gas stove. I have complained to them innumerable times on email on phone calls since 23rd september 2015 but nothing happened till now.
