If we suspect someone of casting jaadoo (magic) on us. How can we break the curse? Is there an aayat? (U.S.A)

The sura ‘falaq’ and sura ‘nas’ are used for exorcism. This statement reported on behalf of the ‘salaf’ is that if someone takes seven leaves of a particular tree and then writes on it ‘falaq’ and ‘nas’ ‘fatiha’ and ‘ayatul kursi’
70 times, blow on it then grind it then mix it with water and drink half a cup than take a shower. For doing this for several days the benefit of it would be that the affects of the magic would be gone.
