Contents of my package went missing at their warehouse

I’ve been waiting for a package since 9-12-2023, when checking with the person that sent the package after 15 , I realised I should have been contacted long ago for this package, tracked the package. It was in Sandton in their warehouse, called n wrote email, I was told it’s at the warehouse, festive season , backlog were the excuse ! 2024 went to postnet to check for me , I was told check after the 9 th the warehouse will be open but is still in Sandton, I tracked the package using the waybill number,PNA*** , no movement on the package ! Today on the 21 January 2024 sent an email after tracking and communication with their online assistant, I was given an email now at night to be told, the contents of my package have been lost and the package was place on the undeliverable pile . Unfortunately I told them I will be writing a review, this is unacceptable , what kind of service is this , it took them over a month to come clean about my package! And they saying nothing about compensation, I want my vouchers, I know what was in the package, we always use their services, nothing like this happens ! Im not happy at all, poor client service and response and no responsibility tajj ooh en at all on their negligence
