Transfer from Nedbank to FNB not refelcting

I transferred money from my Nedbank savings account to an FNB account using the "Clear immediately" option on the 29th of August 2017.

A couple of days later, this amount still was not reflecting so I contacted Nedbank who told me to go to FNB and show them the proof of payment. FNB looked at this but stated that although the account number is correct, this money had not been received by them. Called Nedbank again, only to be told to check back with FNB again. I called again on the 4th of September and I was told Nedbank can do a call back of this amount, where by I would be charged 250. I found this to be ridiculous as there had been no error on my side, so paying a fine for a mistake between these banks seemed unfair and just plain bad service. The consultant i was speaking to said they could also try and trace this with FNB, and that i would receive feedback by that week, latest on the 7th or 8th. It is now the 13th, still no word. Just gave them a call, and still no resolution.

I am very disappointing at this type of service, because I am now short the amount that Nedbank cannot explain where it disappeared off to, plus the charge i paid for an immediate transfer that never was.
