Indane Gas (Domestic Supply) — Delay in supply

I had booked for one cylinder of Indane Gas (Domestic Supply) on 03/02/2010 at M/S Bankura Gas Distributors, P.O- Kenduadihi, Dist-Bankura, West bengal. From last one week they are promissing me daily to send the cylinder when ever i meet them. To day is 21/02/2010. but till date they did not supply the same to me. I have a nine months old baby. i am using kerosin to survive in aabsence of gas.
I am a state govt. employee, me & my family is facing a lot of problems. please look into the matter.
