Indian Bank — debit card charged twice for the same bill and not refunded after several requests

Address: LADIES HOSTEL, VIT UNIVERSITY, CHENNAI CAMPUS, VANDALUR KELAMBAKKAM ROAD, Chennai, Tamil Nadu, 600048

My bill amounted to 205, for the purchase made on 20th february 2019
Tax invoice number : [protected]
Memo no. : 0003737
Tr : 82415

I was told to enter the pin twice since they said the payment was not done the first time. On checking my passbook i figured my amount of 205 rupees was deducted twice. Even after making several requests to bank and big bazaar, they are not refunding the amount.

I am asking for a refund of my money, that was paid extra because of being asked to do so by their cashier.
