There was also a protocol from the child services that a child service worker named Miranda Benson tried to contact them, but she wasn’t able and so, their son was put for adoption. Furthermore, the Kurusus agreed to adopt Harry and they took him in as their son. The Kurusus also asked their son, if Harry wanted a name change, in their private fury, and they became even more furious, when Harry agreed. So, that was the reason why the bonds were replaced. This stupid muggle family had adopted their son, convinced him to change his name and as a result of the name change, he replaced the bonds with them and destroyed any bond to his real family.
