Jinnyat not leaving my sis in law

I come from a religious family, but I never used to believe in Jins. I used to believe that they exist but not that they can harm a human-being. My sister-in-law bought six gold bracelets and right after three hours of wearing them, she got an attack. We took her to many hospitals for weeks and every doctor would say it's all normal. But she would seem like she is dying, couldn't breathe, the attack would come every five mins later. Then one night, I played Surah Rahman and she felt good and then I immediately went and brought a Mulah. The Mulah came and recited a few surahs and he said it's the jinyat. 

When she gets the attack, she feels pain in her feet and can't breathe, she even tries to hold her neck tight and then when we talk to her, she says take us to Ummrah. We promised we will take her to Ummrah in a few months but the attacks still come. We took out the bracelets and she felt well again but today she got the attack again and when was out of the attack. She was crying and said the woman was really scary and they said don't burn the bracelets, I have six of my children in them. We are really confused and dont know what to do. I know, I am taking your time but it's a really serious issue for us and we look forward to hearing from you on this. Thanks!
