Allahabad Bank — transaction declined but amount deducted from my debit card in pos machine.

I have done 2000 rs transaction at mobile shop through my debit card in atm swipe machine. Amount of 2000 has been deducted from my account but shopkeeper said he did not receive the amount in his account. Please reverse my amount as soon as possible in my account. Photo of statement has been attached below. Plz solve it. I am very scared becoz 2000 is very big amount for me.
