Facing problem in pg

Hello sir . I m living in pg for study purpose . But after 1 month I faced many problem like she always intruped me ,spend 2 3 hour in my room for gossp not with me but with my room mates which distrub my study if I ask to owner then she ask this is my house my choice my rules . Nd one imp thing my another frnd belong to sc caste . Thats why owner show rude behaviour with her nd after one after owner say to her that she shift ur thing in open area where owner give a bed almirah to that girl .. but it is open area nd commen area for pg girls .then she denied to change . So now we both want to change pg . I give her security money nd advance money for this month 11 Jan to 11 Feb . Yesterday I told to her I change the room . I inform her before 1o days to leave . But she cut my security money 15ooout of 3ooo . Nd also a rent which I spend day in pg that is agreeable . But she cut security that is not allowed becoz I inform 1o day before leaving . I argue with her .. my frnd also leave this pg nd she inform her before 4 day of leaving nd my tym 1o day but she not take security form her . But she tke from mee just becoz I speak with her rudely .. nd main point in this prob is that schedule caste system . She claiming that girl nd speak on her dressing sences of my frnd becoz of she is sc caste .. so sir PLZZ give me idea what I can do .. there is no agreement in written . She distrub m mentallly . Nd she also no any rule about pg . Bezoz she give room to student 1 tym .. nd she asked about rule from mee .. now she make their own rules .
