The answer to your question is as follows:
Sorcery and black magic should be treated by a pious Aamil. Moreover, if a pious Aamil treats and cures the black magic with the help of the Qur'an and Hadith and asks you to bury the amulet in the soil of the graveyard or he asks you to burn the Agarbatti of dua at home, it can be done.
