[Resolved]  IOCL LPG — Home delivery expenses of LPG

I have one LPG connectivity from IOCL LPG distributor M/s Pragjyoti Gas Agency with the consumer no: 201817.
I have come to notice that I have to pay Rs 350.00 to Rs 360.00 to the delivery boys for a single cylinder whereas the Government rate is Rs 337.00 (approx.). whenever, I argued with the boy regarding this excess money, they just informed me that the deliver cost have to born by the customer.
Through this complaint, I would like to know the IOCl authority that should the customer bear the delivery expenses of the cylinder.
If, this is against your selling policy of cylinder, then what should do as a customer of IOCL.
