“Pending Immediate Payment”

What the hell Discovery!!!!!! I made an immediate transfer to my account yesterday at 10:35 and this normally takes a split second to reflect. It is now 15:25 the next day and the transaction is showing as “pending”. I have made calls to Capitec and they advised funds were released, I have a proof of payment and yet you guys will not release MY MONEY! I was told Capitec needs to send a “financial message”, what is that??? Can you be so vague!! Capitec has never given me issues with an immediate transfer to any bank in South Africa and they have no idea what a “financial message is”. If unsure what and how to resolve this , send the funds back to capitec. This is utter nonsense.
