Currency exchange undo

My company recently engaged in a currency exchange transaction that needs to be undone. The reason for the undo is because of an incorrect amount entered, which was about $1500 . We are looking for someone to help us with the transaction, especially since it is a complex process. The transaction is a transfer and needs to be done accurately so that we can get our money back. We are confident that with the right expertise, this project can be accomplished to the highest standards. The successful candidate must have a good understanding of systems relevant to currency exchange transactions, as well as exceptional problem solving skills.
