No service and no delivery

I posted an important document on the 26/03/2015 at the post office in Musgrave centre I told the staff at the counter that it was important documents to be delivered internationally and I was promised it would take 10 working days.<br> Now AFTER ALMOST A MONTH the documents are still stuck in Johannesburg and no one seems to be able to help me.<br> After intense telephone calls everyone passes the buck and no one is able to help me.<br> The papers that were supposed to be on time is now costing me money. <br> We keep making telephone calls to relevant staff to no avail. Absolutely no customer service. All relevant staff is permanently in meetings or simply do not answer calls.
