Indian Oil Corporation [IOC] — Not receiving subsidy of delivered gas

Address:

Kolkata, West Bengal

With your kind attention I Sanjeev Ganguly would like to state that the subsidy of LPG against Consumer No.CX22880931 is not credited to my Savings A/C since November, 2015.I received Rs.128.18/- on dated 19th October, 2015 which was the last subsidy which was credited to my Savings A/C.I contact with my Gas Distributor & Oriental Bank Of Commerce, Nager Bazar, Kolkata(where subsidy is credited).From Both place, I was told that all the criteria is perfect to receive the subsidy.
So therefore I don't understand that what problem is arrised to give the subsidy.
Please do needful & solve the problem as early as possible.
