We exported a material to USA on 19.06.12. worth $1375.00. It was sent along with two more items in the same Invoice. It was rejected due to a minor issue on 20.07.12. We had claimed DBK which was credited to our bank account. Now we are not going to get the payment for the same. So, I am worried about the DBK which is credited by RBI. What should be done in this case. Please help. Please inform, what would be other implications. Thank you.
