Allahabad Bank — transaction declined but mini statement shows amount withdrawn

Address:

Kolkata, West Bengal, 700068

I charged my debit card for fuel at bharat petroleum outlet. The payment was declined in the payment machine. However, in my mini statement it shows that the amount has been withdrawn twice that I have punched my pin.
I am clueless about how to proceed to reverse the payment. I am adding details, please look into the matter.
