Police not helping in case of domestic violence

On the 15th August, my sister got beaten by her husband on insist of her mother in law. Issue generated because of something related to home disturbance and volunteerily disturb by his mother in law and father in law. And my sister went to my relatives home after her husband beat and let her thow out to home and the. Called us. We are living in Gujarat so after our family got to police station police shown negligence on his work as per police women's said your husband may beat you but have to bear it and we said no then they ask us to sign on N.C.R which is crpc under 155 and IPC 506,504,323 as we are confusing why then not issue FIR instead N.C.R and police is not solving issue we need and women's help organisations or seek what we do, do we ask to give written statement to us to police madam as we literally understand she got corrupted.
