SA POST OFFICE NO COMMUNICATION!!

A package was unfortunately posted to me from the UK. I paid extra for track and sign postage - whatever that may mean. It was sent on the 24th May 2021 and I have used Track my Parcel to see where my precious cargo is - the last update was the 19th June and it basically tells me nothing!!!!! HOW DO I FIND MY PACKAGE, IT HAS BEEN MOST FRUSTRATING and just as I expected most disappointing service from the Post Office.
