I still don't understand the problem even thought you've posted your message four times!
So...basically...You have a friend who wants a maid, right?. You find her a maid but she doesn't pay her salary...so you do. Then she sends her back home because whatever reason and she wants you to pay the airfare or else she goes to the police? Errr. ok whatever, she can go to the police, so what? you haven't done anything dodgy, have you?
