Not sure anyone has this problem or not. When I linked the facebook to my phone, then my phone book is overtaken by their facebook contact information (but their's phone number on the facebook is not correct), so I couldn't call them or text them, as all the phone call or text are going to the wrong number or incorrect number. Well then I unlinked them , but on the message system is still using the facebook number... I couldn't reply their message directly. Have to go to the people, contact information, click send message... So annoy... Anyone knows how to fix it?
