Customs&EMS are an absolute mess combined!!!!

I was told that it would take 2weeks for my parcel to be sent to South Africa from Nigeria, it has now been over 5 weeks. The last tracking status on my item says that it left Lagos on the 25th of January - there have been no updates since. I have called EMS in Nigeria numerous times and they say my item is at customs in SA and that the exchange office will call me By Monday this week, that didn't happen. I then called the International Mail people and I get different stories. So I called EMS in SA and they said Customs will call me by this week as the item has arrived, since this didnt happen, I called back numerous times and they told me that the item is still on route from Nigeria, I explained That I was told by THEM that it had arrived in SA - they then said that whoever told me this **** (But they told me this!!!) I keep calling and they keep disregarding the fact that THEY told me the item had arrived in SA, and keep telling me theres nothing they can do it hasnt arrived - no one will look into it!

I'm very angry at the lack of consistency and lack of information, I am worried that my item is stuck at customs because of a fee Im supposed to pay - but how will I pay it if they dont let me know?? The tracking portal has not been updated in over a month, Ive been calling and I get different stories each Time with no proper resolution - basically no one knows whats going on and no one cares.

This is a nightmare.
