Cannot get the address right

From the start of this transaction we have had issues, in Germany the agent who was meant to collect the documents could not get the time right for collection and took 2 days before the package was collected. He didn't know what he was doing and even thought the postal code (in SA) was the cost in Euros?!?! The package was meant to be delivered today (11.06.2015), the package contains urgent documents needed for a visa application tomorrow (12.06.2015). When tracking the package it stated address issue and I called DHL SA, only to be told the address contained the road and province and they could not deliver it. My dad sent me the picture of the airwaybill and it has the full CORRECT address on it. Therefore I do not understand how this could go wrong. DHL then advises for me (the receiver) to complete and send documents & they will re-send it. I do this and now I am told that my dad (in Germany) needs to send the forms and docs required to \redirect"the package not me!! This is completely unacceptable"
