Indane LPG Gas — non availability of LPG after online booking

I am a consumer of LPG gas (Indane) having consumer No.3472 and the agency is Global Indane Bhubandswar. I draw the gas on 30.04.2012 and online booked gas through telephone and they given me the srl. No.3126 dated 07.04.12. when I contacted the Glable office in person and asked about the gas cyclender on 28.05.12, they gave another booking No.9338 by cancelling the earlier booking No.3126 telling gas will gave you from 2/4 days of the fresh booking. But no gas cyclener has since been given to me even after lapse of one month to draw the gas on 30.04.2012. Now the gas is going to be complete soon and how can I will manage where as I am having two cyclender connection and gas has not given me timely since two to three months. In this connection who is the responsible for this type of irregularities. When one booking srl. No.3126 had given me on 07.04.12 by the agency where the gas has gone which was booked against srl.3126 dated 07.04.12. I surprise when they gave me another booking srl No. 9338 on 28.05.12 telling the earlier is cancelled. This is at their discretion to cancel a booking and issue another booking srl. number. We are being poor consumer what can do. Hence request to solve the problem, where the gas cyclender is most important and problem one in Bhubaneswar. Hope a favourable action please to avoid such illegals.
