D-Mart / Avenue Supermarts — Failed transaction at pos d mart satara road pune, maharashtra

I made purchase at d mart satara road branch on 27.05.2017 against visa debit card no. [protected] of dena bank valid from 01/16 to 01/21
For rs.1890.36. On swiping the card there was error and slip showed that txn failed sale declined. However my account was debited twice by rs.1890.36
Therefore i made complaint to dena bank. They have informed that there is no credit pending. I therefore i request d mart to check their bank account and check that whether there is double credit on 27.05.2017. If so arrange to refund an amt. Of rs.1890.36 for failed transaction.
