Temu Refund Missing: Money Not Returned to Bank Card

My name is John M*** and I am a Temu customer in South Africa. Today I placed an order for a total of 596 using my bank card. Out of this amount I am expecting 396 to be returned to me, but this money has not been refunded and is still missing from my bank account. I request that Temu urgently checks this transaction, returns the missing 396 to my bank card, and informs me in writing once the refund has been completed. I can provide bank screenshots and any other necessary information if needed.
