    After dating a girl online for over 4 months, and having some plans to meet (I live in an other state), she was starting to ask for more and more money. I contacted acm investigations to verify her identity, and after a few days, got my answer. I was getting scammed. I’m glad I used them before wasting more money on her. Very friendly and professional investigator.
