I have bought prestige glass top two burner gas stove on 20th sep (Last friday) in ambal store, medavakkam, chennai. After using the stove for an hour got the noise in the big burner, i have turned off the regulator then drained entire gas from tube and turned on, after that stove was working without any problem, we didn't used the stove for couple of days and today tried to turn on the big burner it's not releasing the gas.
Kindly check and revert
