24 Hours after cash deposit and still not avail

I had a very bad experience with nedbank on the 07/08/2015. I deposited money into my account on the evening of the 6th of Aug at 19:43. I then received an sms stating that the money is available. I then log onto my Internet banking 24 hours later to a shocking sight. My money that I deposited still not reflecting. This was not a envelope deposit and was a cash accepting atm with a prompt showing immediately available. I then call the call centre and get transfered to telephone banking. After verifying my details the guy checks on the system and he tells me sorry sir but I cannot trace the funds. I was ****ed of because I cannot access my own money nor is it reflecting and now I have a man telling me he does not know where my money is. At this point in time it makes me feel disgusted because what if it was an emergency and I needed the money and I swipe my card with a answer of decline and to top it off no one knows where my money is. Imagine someone telling you they do not know where your money is. I am a banker that various banks for the fact of convenience of payment as people transfer money all the time and for the four years of my banking experience this is utterly the worst..
