To pay the refill. I made the payment on date: 01/09/2019 and the transaction was successful

I paid the amount rs.588.50 via the above link and got the successful transaction message. But when the gas delivery came the distributor denied for the online payment received confirmation. However, the amount is deducted from the bank. Please help me in refunding it.
