national prosecuting authority of south africa

<br> I've been trying to send them emails since thursday 30April 2015, but i wasn't going through even their office lines they rang but no one answered. So today i said let me try my luck & see if anyone will answer and they answered they transfered my call to the HR DEPARTMENT then i asked the lady if there's anything wrong with their lines because i have been trying to send them some documents and its not going through, she just said \i dont know what you are talking about because our lines never had any problems"i nisisted that but i have been trying since last week"
