Refund stuck in Payflex wallet, no support from Payflex

I have been a loyal Payflex customer in South Africa for a long time without any issues. Recently, I returned an item from Takealot, which was correctly refunded into my Payflex wallet (around R800+). The amount shows as available in my wallet and is not pending.

However, when I make new payments via Payflex, this balance is not automatically deducted, even though that is how the system is supposed to work. As a result, I am being charged in full instead of using my wallet balance.

I have tried every channel to resolve this:

Emailed Payflex → No reply.

Called multiple times → No one answers.

WhatsApp support → No response.

There is also no option on the Payflex website to update my personal details such as mobile number or email address, which makes communication even harder.

This is unacceptable for a financial services company. I simply want my available wallet balance to be app**** to my payments, as per the agreed process.

I request immediate resolution and for Payflex to honor its own system functionality by applying my wallet balance to my outstanding payments.
