Worst service ever

The worst service ever experienced today. I pay R455 service fee per month for private banking thinking that a personal banker will handle my problems. But never happened. I made a loss of R5000.00 because of given the run around and Mpho who really did not take my matter seriously. I did a transfer from my FNB account to Nedbank and paid for the clear and pay immediate payment. A service which does not work but that I paid the fee.I purchased a used car from Mr Botha private sale. I did the transfer at 12.50 this afternoon. I waited 15min and no monies was transferred. I called my so called personal banker Mpho. He Said to me it will take up to 2hours to clear. I was shocked and informed the seller. Anyway both parties agreed to wait. I need the car and and seller needs his money. We waited till 3pm. Called Mpho who transferred my call to call center. I was called around 5.30pm and was told that the call center tried calling me at after 1pm. And said they could not get hold of me. Why did they not continue to try. I was waiting patiently for a call I needed to resolve the payment. Why would I ignore the call. I lost the deal, I lost the profit of R5000. Because of this. This is not service. I will be publishing my story on media platforms. Finally Will get my lawyer to advice me further. This is how customers get serviced. N.J.Carrim ***
