Justice and honesty

lLast night I was chatting with a girl from Ghana, that was so interesting for me to talk with a girl who is black and she is from Africa, rarely I've visited African people and I know nothing about their culture. At the beginning of chat she told that she has lost her parents in an accident and she lives with her uncle and her uncle doesn’t pay for registration fee in school and has been sacked from school because of this matter. She asked me 70 USD for registration fee. I told her give me address of school or bank account number of school, but she denied and she told that they will punish her if she do so. I told her that I will talk with Iran embassy in Ghana about this matter, but it seemed that is not her suitable way.
Now my mind is busy about justice in the world , if she is honest and I don’t pay to her I will feel guilty and if she is not honest and I pay I will feel idiocy about myself.
What can I really do, how can I know her and be reassure about her honesty.
