Plenty of truth to this Dave unfortunately. I've seen it at least 5 times now with my clients. You normally have to go through an extra security step to send outside of your accounts, as it's not an internal transaction, so that's why they ask for you to do it manually.
Perhaps I was a little dismissive Wayne but there was a lot of information missing from the original post.
It's a terrible situation to be in and I sincerely hope that no one I know ever gets conned out of any money, large sums of small.
