Indian Oil Corporation [IOC] — gas vendor complain of indane gas

I am consumer of m s gas service agency of indian gas and resident of lalji tola, devi asthan, patna (Bihar). I am facing lot of problem because of delivery man. We have asked him to bring the full gas cylinder but till now he does not bring. He delivers always short quantity of gas but nobody taking any action against him. One of the person name pappu kumar s/o late basudeo prasad who is the resident of lalji tola, devi asthan, patna collabrate with your vendor for this kalabazari.
So please take a necessary action against him i have already request to him please replace the cylinder but he did not. I hope you will take necessary action against him. (Ye gas nikalne ka dhandha lagbhag 10 salon se vendor aur pappu kumar ke milibhagat se chahl raha hai jisse aam public ko kam gas mil raha hai.)
The company does`t pick phone for this and all the other time their phone is always busy. They are deliver short weight of gas always.

Thanks & regards
Your consumer
