Indane Gas Lpg — Emergency no. not working

Address: North Delhi, Delhi

I changed my refill of LPG tonight, only to find the leakage continuously going on. I switched off the knob, and tried calling all the emergencies no. given on the refill slip. The nos. are 23841235, 23846548, cell no. [protected]. Non of these nos. are functional. I even tried calling customer care, but it was of no help either, Just in case, if accident would had happened, then who would be held responsible for it? How can I claim compensation for the above flaw in lack of essential services by Indane?
