Indane Gas Cylinder — they are charging more

Sir,
My name is pradeep kumar and my gas connection no.in indane is ME32558 with Mukund Enterprises, barakpura, hyderabad.
Recently on 04/03/2009 i received refilled cylinder from mukund enterprises. The deliveryman gave me bill for Rs.304.40 and charged the same amount. When i asked him that on your bill it has printed at side that some subsidy of Rs.50/- is being provided by A.P. Govt. then he told that we are charging Rs. 305/- after that subsidy less.
Sir Whereas i have listened that govt has reduced it to Rs. 255/-. Please clarify that.
Even whenever you make any call to that office again they will tell you Rs.305/-after less.
The subsidy ramark is given at side only to manage the govt.instruction and to cheat the people.
This is pure insult of govt. instruction and they are demaging the image of govt.also.
Please do something with HONEST ACTION.
