No rolling updates of package location.

I ordered a package with the tracking number RZ***GB from the UK on this date 02/12/19, it got to JIMC then to the JHB International Mail Centre ( Hub) on the very same day as ITEM RECIEVED and INCOMING INTERNATIONAL which is 13/12/19 at 09:03. Further on and the last update so far is on the 16/12/19 at 12:11 it said JHB International Mail Centre (Hub) IN TRANSIT. So first of all where is my package now as it is 24/12/19 and why are updates running so slow? I mean updates like it being at SARS or on its way to the Cape Town Hub would be fine. And PLEASE tell me by what date (approximately) will the package be at my local post office.
