HP Gas Cylinder — Delay in delivering the refill in spite of booking

Address:

Pune, Maharashtra

I booked for a refill of my cylinder on the 6th of January 2011 and till date that is 14th Jan 2011,I have not got it. Inspite of reminders I have been told that the delivery will take another three days. Am I supposed to understand that gas delivery takes more than half a month??
My consumer no is :648494 , my booking no is 1399 at Kiran Hp Gas Agency,9 Anchor House,Kondhwa Road,Pune-411040.
