General,
You hardly see them because there are hardly any disputes when it comes to paying especially with books in Australia.
I remember a poster a while back having a dispute with Canbet and received a very long letter from the Australian government. I don't recall the outcome however.
General if you have ever been to CR and see how things operate here, you wouldn't send money to anyone unless you knew them personally.
Just last week, my friend nearly lost over $500,000 mortgage on his property because the buyer bribed someone in the registry a $1000 to mark it as paid.
