Payment was deducted but remains unallocated

I made a payment to Takealot via Ozow. The payment remains unallocated and the status of the order remains 'awaiting payment'. Ozow refuses to assist, even though I've provided them with the proof of payment (the payment was deducted from my banking account). Their answer is: The ball is in Takealot's court, even though the payment was made via their portal. I will not be making use of their payment method ever again, as based on my experience, it can be unreliable and when it fails, we don't receive supporting in the form of them being willing to liaise with the merchant.
