Proccessing visa from a foreign country

Hi
I am a Zimbwean student studying in South Africa and i am unable to go to Zimbabwe due to academic reasons but i need to sort out my visa to beijing for a university program.Can i apply for my visa online or send my documentation to someone in Zimbabwe who submit for me as the embassy here in South Africa stated they are unable to do it as my study permit expires in December.

I am looking for the email address for the Chinese embassy in Zimbabwe.The ones i took from their website are not working and i urgently need it.Thanks
