old id book not good enough despite living in south africa 56 years department of home affairs dont recognise me ??????

What a load of ****. I have lived in south africa for 56 years and now because my id document is old the home affairs wont accept it??????? Yet it accepts immigrants in the country quite easily not good enough, i have my own house, my own car, a south african drivers licence and no one has turned down my id book just because its old so i am basically living in south africa with an id book but you allow immigrants to join your bank no thank you
