Incompetence and lies. I want a refund

I wanted to courier legal documents from Secunda to Cape Town for next day delivery. I emphasized numerous times it needs to be delivered the next day. ONC<br> 3 days later and the documents are still in Johannesburg.<br> Zandile **** to me on a few occasions. Firstly by stating that Postnet doesn't work on Saturdays although it clearly states on their door and on their waybill that they are open for business on Saturdays. Also, I have had packages delivered on a Saturday. She then **** to me at 9;15 this morning saying my documents were in Cape Town when the system clearly indicated it was in Joburg. Contrary to the system she still stated the Documents were in Cape Town. I asked for a refund as I did not receive the service I had paid for. The manager is completely not interested in the branch as it took Zandile nearly half an hour to get hold of him. Zandile refused a refund and I was told to come back tomorrow as the manager didn't want to see me today/.<br> I am not asking for anything else except the service I paid for which didn't happen. This lack of service puts numerous other tasks in jeopardy now.<br> Simple, I demand a refund. I din't receive the service I paid for
