Indane Gas — Use of expired cylinders

Address:

Lucknow, Uttar Pradesh

I am a customer of indane gas for the last 12 years my gas agency is domestic gas service sector-o aliganj.
Agency is providing expired cylinders as there is date mentioned on every cylinder like B 11, A 10.
which means cylinder is not fit to use after that date i.e. B 11 is june 11 but still gas agency is refilling the same cylinder and delivering the gas which is dangerous as the cylinder can explode then who will be responsible for it.
even after asking to replace he will not replace and say that this ok and all are doing it.
indian oil you should take action against it if not tell me i wil go to senior management and further.
