Consumer Redressal

Hi Sir, My name is Arunkumar. I am residing in Madinaguda, Miyapur. I applied for a new Indane Gas connection on 7th August 2014. The agency name is Sri Saila Gas Agency, Miyapur. I opted for the gas connection with out gas stove. They got an amount of Rs.3500/- for that. In turn, they did not give any receipt or bill. They just gave the lower part of the New customer form with a mobile number written on it. After 15 days I got the Gas Cylinder, pipe & the regulator. But, till now I did not get the subscription voucher or consumer number. It has been almost 3 months. Still I did not get the subscription voucher or consumer number. Whenever I contact the gas agency,they are saying that I will get the voucher in 2 days or 3 days. They are just dragging it. As of now, i don\'t have any proof or evidence for Indane gas connection. Please help me out in Sorting the issue. Thanks, Arunkumar J
