Time to take legal action

I have been expecting a package in Musina for over a month now. The package was last scanned in Musina 3 weeks ago & when l went to collect the manager said the package had missing documents and he returned it for verification. However this is not the first time he does tjis process of returning packages and later npt receiving them back. In 2010 l lost a package the same way amd was only paid by my insurance yet he is the one to blame. Why does he always return our parcels amd on return there is no proof or accountability as theu are not scanned at their return destination. I am tired of calling phones that are never picked up amd have used over R400 holding on with a machine speaking. I have sent 2 emails in the last week and non of them have been reaponded to. I need my package urgently and it contains things that will soon be useless of l do not get it on time.
