No service from JIMC

I ordered a parcel from Indonesia with tracking number RR*********ID which was shipped on the 10th of January 2020, it arrived in South Africa on the 25th of January 2020. Now if I track my parcel on the Domestic tracking system of the Post Office it says that the parcel is still at the JHB Int Mail Centre Hub but if I track my parcel on the International tracking system of the Post Office it says that my parcel has been dispatched from the JIMC on the 3rd of February 2020. I have sent countless and countless of emails to all possible email addresses on the Post Office website but I am not getting any response from them. I have spoken to the people at the post office and they have not received my parcel yet. The strange thing is that there is no south-african tracking number associated to this parcel?!?!?!?Are the people working at the JIMC *****ing our parcels???
