Hp Gas — money deducted from the account for the hp gas but the gas station say they can see no payment made online!

Address:	Thane, Maharashtra, 401504
Website:	Paymantra

I paid Rs. 759.94 for the gas on the link sent with the message which was Paymantra. I was still charged by the gas station saying that if is paid online they have got no information so I had to pay him in gas. I did not even get the refund of the amount nor the gas. The gas station people checked for the transaction online in their system which does not eben show any transaction made online by me.
I am attaching the picture of the transaction confirmation and also the pictures of the online hp site and the receipt I got tor the paymrnt in cash.
