It is sad that even today all card providers do not have support for Africa, it seems that the world is only in Europe and America
I used to do online marketing, years ago.
I remember the highest priority and highest value has always been for countries where more is spent online. unfortunately, most of Africa is not, so it was a waste of resources. You can't get almost anything from there.
also, African states are very conservative and closed for the foreign financial sector. It's going out of their control and governments don't like it.
