Abuse And Blackmail By relatives

My wife's relatives separated us and now they completely brainwashed her. They blocked her every communication with me. Now they are blackmailing me to remove her photos from my Instagram account. And they are abusing me and spamming my phone with abusing messages. I gifted my wife 35 kaasu gold. Now they want divorce from me. But they are not happy to return my gold back. I haven't taken any dowry from them. I am saying them I want to stay with my wife. Now my wife is also not talking with me, only their relatives talking with me and saying she doesn't like you, give divorce and also some alimony. What can I do now. I want to lodge a complaint against people abusing me. And I want my gold back. What shall I do?
