I am pnb account holder with account no-[protected]
Debit card ending with (* * * 1448)
Of kundli branch (Haryana).
I have swiped my debit card at chunniwala patna on march, 6, 2019.
After swiping my card i got a debit message of amount 17800. But simultaneously transaction failed receipt was generated at chunniwala shop machine.
Therefor i have swiped my card again for the same amount of 17800.
This time receipt of acknowledgement had been received.
I have lodged my complaint in pnb bank as well to refund this amount asap.
