Not all countries have the same PayPal features and functions - this is because each country has their own financial rules and regulations. South Africa PayPal Accounts do have the capability to receive funds therefore assuming you have a US PayPal account and it's "verified" you should be able to send money. However, if your PayPal Account is "unverified", then there are limits on both sending and withdrawing funds. As we have no details about your account setup or the account setup of the receiver - it's simply only a guess as to the root cause.
