Wazifa for protection

I am in a great grief. Need your advice to solve my family problem. Please help me for the sake of Allah Ta'ala. The problem is that my chachi has done some asrath on my father that he has stopped speaking us and doing whatever chachi says. I am not getting wether he does it because of asrath or because of his arrogance. Dad broke relationships with my aunts and phupis. Now the situation is that we cant go to any relatives home and they are also not Allowed to come here. All are saying that chachi has done black magic on him because she does it often on others for her favour . I have browsed many dua but it says to blow on water or to blow it on oil and apply. Therefore my dad is not coming close to us that we can give him dum water or apply dum oil on his hairs. Please provide any powerful dua to finish this asrath and get my dad back to me.
