Hello, two months ago i participated in a collaborative fashion event as a designer that was poorly organized. At the end of the event one of the model got lost in the crowd and we got separated from each other, she then left without trying to contact me. The problem is that she left to another country. I have been trying for the past 2 months to arrange a return but she is barely replying (through instagram), after several people advising me to do so i also contacted her agency a week ago but i also didn't get an answer. What should i do? I really want to get it back as it is a unique model and i spent a lot of time on it.
