Settlement paid but still no confirmation of settlement

I recently traded in my vehicle and now financed somewhere else. The dealership made the payment on my settlement yesterday morning 08:05 from FNB and I also have the proof of payment. They sent through the proof of payment and so did I to the service email address yesterday morning and today again. Phoned yesterday and today and was told no payment has been received yet. The settlement quote we used expires today and my installment was taken on Saturday for the previous vehicle, since the settlement has been paid in full I would expect a refund of my installment taken. I was told that to phone again tomorrow(today and yesterday) to check payment, still my account is open, can someone please assist to get this sorted asap and that the account can be closed/settled and I be refunded my installment. I will forward the proof of payment to whoever can assist me directly please so this can be handled and done with. I need the reversal done asap as it would not be fine with wesbank if I owed you any funds but its fine if you owe me, please put yourself in my position and think of the impact it would have had on you if this had happend.
