Hi, I am residents of Ambuja Housing Udyan, 1050/1 Survey Park Kolkata-75. The LPG Indane Gas provider provides the Faulty gas cylinder prone to gas leakage. They have given us emergency contact no for the same, Unfortunately no one pick the on following given number multiple times. I think provider have to make sure they deliver the defect free cylinder or make some one available in case of emergency of gas leakage.
