6months continuous lack of service

I see the telkom van parking off out our exchange and driver sleeping . when i stopped him he told me hes on lunch and this aint his area. I must not complain to him when i demanded his name he sped off . I didnt think of his number plate at the time but ill recognize him again when i see him . But the issue still when the **** are they going to fix my line . nobody even calls to let me know of progress . when i call it in I get cut off when i demand an answer . ??? ***
