Indian Bank — unauthorized transaction

Address:

632014

There was a unauthorised transaction from my account of ₹1713( debit card) on 31 march 2019 around 3 evening

I've contacted the nearby indian bank branch and they said that the charge is voided but I can still see the transaction in my bank statements and still I didn't receive any refund from them

So I request u to please acknowledge of the issue and help me bringing back the funds
