[Resolved]  Indane Gas Cylinder — Badly dented and rusted cylinder

My Consumer Number is A19746 and take supply of Gas from Agnihotri Gas Service, Sector 37 NOIDA
The cylindrer supplies as refill to me against their Bill Number 177 dated 01/05/09 is rusted and dented all over. It is impossible to see any marking on the cylider. I am very apprehensive about connecting the cylinder and its use
. Request made by wife to the delivery man to change the cylinder was not accepted .
I want some responsible person to come and have alook at the cylinder and confirm that it is safe to use that cylinder and if possible change the cylinder
