I wouldn't give her any money to send to her family - she earns a salary and I heard about many many cons like that - sick mother, sick father, funeral and money needed for that.

And I would deduct telephone bill money from her salary - she wants to speak, she has to pay. Otherwise it will continue.

And I would tell her that if she once again leaves without telling me about it, she'll go back home. She will be scared and hopefully won't do it again.

Beadaebok is right, show the maid the boundaries, respect her and demand respect back.
