My partners family havent seen my daughter since she was a month old because they simply dont care, theyve started takin pictures and posting them of her acting like happy families, they dont even know if shes okay! Ive asked them to remove the pictures and they refuse! It sounds pathetic but they dont even act like aunt and a nan to her so arguing that point is ridiculous! Can i go to the police as theyve refused to take it down and they dont have my consent???? 
Also im in corfu at the moment and my partner stormed off and hasnt been back for 5 hours, its a family holiday so my sister keeps having my daughter whilst i go out looking on my own but i dont know what to do, anyone been to corfu before and know where someone would go????
Thank you
