Indian Oil Corporation [IOC] — leaked lpg gas cylinder for household

Address:

tp-13, opp chhani jakat naka, baroda, Vadodara, Gujarat, 390024

My consumer no. Is 6268. 50 days back i booked and purchased a new lpg cylinder as a spare cylinder. My active cylinder got over and when i took the spare cylinder to use the same, i found the weight of the cylinder to be very less. I checked it to find the gross weight was less than 16 kg. I didn't even break the seal. I called the gas agency, but the person said that we should have informed before inhand within 3 days after getting the cylinder. This is the extra cylinder which we keep as spare and it was kept away in upstairs and we were not even knowing the leakage. Now, we have paid full amount and got a new cylinder. Why do we have to pay though it wasn't our mistake at all. We tried to call you through your toll free no. For clarification several times but, couldn't get the connection. Suppose if something has happened and some accident has occurred, what we will do? Kindly ask them to return the money we paid for the cylinder.
