The South African Post Office has suspended its “services” to Russia, “The” Ukraine and Belarus.
The South African Post Office has long been so entirely dysfunctional that you would rather spend seventeen times the price to a private courier, but at least your package would actually get to where it was supposed to.
Quite literally no-one will notice that their service to these countries (or anywhere else) has been halted.
Also, please note the bottom paragraph, in which South Africans are once again advised to obey the rules for doing things when doing things. Just like this.
