Worst Courier Service in South Africa, very disappointed!!!

I was send a package last week Tuesday from Pretoria to Cape Town, overnight package delivery but I am still waiting for my package. I tried calling but non of the numbers work, I send a email and still waiting for a response, I had a chat with there chat box and they seems not to be able to find my package. I would like to speak to a human being that works at Amarex. To find out where my package is. I am leaving the country on Wednesday and I do not think I will receive my package before then. The worst courier service in South Africa. I should have use The Courier Guy, everyone says they are the best service and they communicate with the customers.
