Hi @FrancoiseV ,
Sorry to hear about you struggling with payments on your store. Something great is that you are getting orders from all around the world but lets look into seeing if we can help you receive your payments better.
Can I ask where PayFast was recommended to you? It is in the list of gateways Shopify is partenered with in South Africa, but Shopify wouldn’ thave any control or say on how a third party payment gateway would work. Have you reached out to PayFast about this at all? PayFast is a South African gateway and maybe that’s why there have been issues with international payments. You can reach out to PayFast directly from their support here to discuss with them directly.
Alternativley if PayFast isn’t enabling you to recieve payments for your international orders, it could be worth your while to investigate using another payment gateway in the list. I know 2Checkout definitley do international payments. Would you be open to possibly changing payment gateway to get this working better?
