Draydis, you know with the info you've given about your girl, her profile is easy to find. I think the email address is probably setup by the agency ... my experience is they all use QQ and more. If it is her personal address, then she uses yahoo messenger, try that route. But if the address sounds like firstname-in-English.surnamename and some number, the agency set it up. My experience with that agency is that they will block direct contact as long as possible, it takes complaining and threats to get direct contact, I tried on a couple of occasions, always the same story.
She is young ... more risk of a scam than with older ones.
My 2 cents ...
