Plzz tell me....

If a fake and false case of Dowry and Domestic Violence is going on in and in between the girl's grandfather filed a fake and false police complaint that I am giving threats to them on phone but dont tell that on which phone number I am giving threats.. My questions are: 1. Can I obtainaed copy of complaint from the police which the grand father of girl had given..is their any legal way 2. When I asked the concerned inspector regarding the copy of complaint he refused to give and said it is not possible....Is he right? 3. In the complaint they had given my number but not given any number on which i my giving threats,can I ask to provide me that number? 4.Is there any way to stop this kind of fake complaints in future? Actually I am.fighting all the cases on merits and now their cross examination is going to b held on next date..
