My girlfriends father is refusing to return my phone. He has gone through it without my permission and contacted my mother. He told her that I was living on the streets which is not true. He told her that I stole from him which is also not true. I don't remember what else he told her. My mother has a heart condition he could have given her a heart attack. I went to see him today May 30,2011 and he refused again to give me my phone and stated that since he couldn't contact my mother about the phone that he would contact my dad but the phone in question is mine I paid for it. He says that he didn't get their numbers out of my phone but I have witnesses that he not only got the number out of my phone which he knew was my property before he went through it, but that he also went through all my text messages. What can I do?
