Stupid outdated rules

Krugersdorp home affairs refuses to assist me to change my surname siting departmental regulations . My mother married my stepfather when I was a tiny child and he was the only father I ever knew. Now rhet he has passed away I want to adopt his surname in honour of him but the department of home affairs refuses stating that a living family member must accompany me to agree . My father had only one sibling and she is also dead. So home affairs refuses to assist. Only my mother and half brother remain but they live in Belgium. I want to change my surname and this stupid archaic regulation is so stupid and outdated . I am highly disgusted at their lack of empathy.
