Blackmagic Case - Need Legal help in this case

Our family has been under lot of negativity, subjected to conspiracy with our thoughts being captured through unknown means (telepathic or any unknown means) from many years without our knowledge. (Confirmed by our natal chart through an astrologer- as well).I started hearing voices of a known set of people (initially 4(known family ppl , classmates, college lecturers,relatives,neighbours) 5 years back and voices appear to be outside the body,within,from surrounding vicinity.The voices diminishes in strength and sometimes increases severely (unbearable) and it is not location specific but the voices,messages or disturbance communicated through unknown means varies in intensity .This started in the year 2011-12 and a form of paranormal harassment.The intensity and strength of the voices is more at the current residence and this occurrence of problem also after shifting to this place. There are lot many people involved in this attack-but all are among known set of people.
