Indian Bank — pos

I had swiped my card in kfc, phoenix mall, mumbai for a payment of rs.634 but they wrongly entered and took the amount of rs.6340 from my s/b account on[protected].

I asked them to refund the payment but they said that we made a void sale receipt, so that amount will be transferred to our account automatically within 2-3 working days. Till today the amount is not refunded to my account. How many days it will take to refund the money.

When will the amount will be refunded to my account.
