Mental harassment

I am a sub inspector in capf.i live in ladies hostel of my organisation. constables and sub officers leave together . 2 constables Live in one room and sub officers single .as being sub officers we are given larger rooms than constables. Hostel in charge said us if u guys will shift to small size room u can live easily in rooms, but 2 constable in small room face problem. All 5 of us agreed to change our room so constables could get more space to leave. me and my one colleague shifted our rooms but rest of three refused to shift there room. After that i demanded my old room should be returned to me but hostel incharge denied to do so.she said your room will not be returned ,then i said other sub officers' should also be shifted to smaller rooms because we are force personnel and rules should be same for all. She refused to do so and after that started making fun of me.she often comments on me for this incident and passes sarcastic smile to me. I complained to head of our unit but he said" i will not interfere in girls matter,. I want to file a case of mental harassment against hostel incharge can i do so?
