Indian Oil Corporation [IOC] — my booking is being cancelled without proper reason and bad behaviour of the delivery boy

Address:

Kolkata, West Bengal, 700159

I have done the booking on 8/8/17, booking no.887949, on 10/8 got msg that cylinder will be delivered shortly, tdy got the message that my booking is cancelled, without any reason.
On 17/7/17 when the delivery boy came to deliver the cylinder he demanded Rs.650, where the cost of the cylinder was ₹584, he said bluntly that ₹66is the delivery charges n I am bound to pay that.If not from next time they will not deliver the cylinder.
Hope for the fairer decision from ur side n that too soon.Thank u
