Submitting Additional Documentation to Consulate

[sege5641 0]

So my wife had her interview a couple of months ago and we forgot some of the forms. But now we have completed all the forms and are trying to send them up to the consulate in Johannesburg, South Africa.

I see on the green sheet we were given at the interview it states "The U.S. Government will bear the cost of returning your outstanding documentation to the U.S. Consulate." Both phone numbers listed on this sheet for the Visa call center and DHL within the consulate are disconnected. I have spoken to a couple of people at the consulate some don't know what I'm talking about and others give me additional phone numbers to call. I did reach someone within DHL that knew about this but was unable to help because she would have to give me the consulates DHL account number to charge to their account....

Now after all this I found http://usvisa-info.com/en-ZA/selfservice but still this site talks about "Submit Documents to Consular Section" but does not have any option of creating a shipping label or any other information. I have clicked every link this website has and four hours latter I relies it is just another game from the State Department.

So how in the hell do you send documents up and get the consulate to "bear the cost"?????
