GEO payments still not reflecting 23 hours after my vehicle was privately sold and handed over to new owner

As a FNB |Customer I've trusted that my transaction regarding the private sell of my car to buy another one would be at my best interest and that my bank would have my best interest in mind. Transaction took place at 15:00 17/3/2021. I've sold my vehicle to a private person from Limpopo. I've suggested GEO payment since the money could be available right away and before they took the car. The procedure was followed and the money was deducted from the buyers account. After 23 hours no money is till reflecting in my account. I've phone FNB and where I was told that I have to give the person that I don't know at all and ask him to follow up at his branch what is going on.. If this person or perhaps ******* find out they have my car and their money is still not allocated what is prohibiting him not paying me.

This is UNACCEPTABLE if the payment by means of GEO payments are there to ensure no loss to FNB customers

Please give urgent feedback where this amount of R157000-00 is currently allocated to if not reflecting in Account ***
