Corporation Bank — amount debited twice for one transaction

Address:

Lad Nagar Pandharpur, Solapur, Maharashtra, 413304

I purchased some groceries on 8th March from super bazar near kbp college Pandharpur.
The bill was 380 rupees. I swiped my debit card debit card only once. But 380 rupees was debited from my account twice.
Accordingly I received two messages. And the amount is seen to be debitted twice.
But the super bazar cashier claims the amount has been credited in his account only once. While bank employee, when enquired is telling the amount is credited in the account of super bazar account twice.
I am neither unable to get the amount return nor bank or super bazar is taking the responsibility of the same.
Pl. Guide.
