Western union will have checked her id, yes, but I don't think they would release any details to you. You say you have studied law and have a contract which fully protects you, can you explain who offers protection and under what circumstances. You will not get your money back from her and any efforts made in Tunisia would probably cost more than you have lost.
Yes any chat made throught emails and negotiations take the same effect as a paper contract
So the agreement between me and her is a contract .
I have mentioned before that I don't want to go legal with her I just want someone to scare her that it will be serious and legal so she would be scared and return the money.
I need help so please be positive
