Unpaid Refund from resolved Debit order dispute

I have a debit orde which the dispute was resolved successfulland the funds were supposed to be refunded into my business account within 5 working days. It's gone past day 7 and FNB hasn't refunded me the funds and no one can help I keep calling non of the consultants seem to know what's going on. I even spoke to the chanel manager Sbusiso Cele who tried to assist and pushed rhe managers to call me to resolve this. One of the Mangers Kendall called he said hus escalating and he will sort it out soon. I thought they would resolve this immediately given that they mislead me az a customer and went over the turn around time but I'm still waiting as this hasn't been resolved yet..FNB is very *********** especially its business telephone consultants no sense of urgency what so ever and are making us small businesses suffer even worse when loading shedding is already taking a toll on our businesses.
