Nedbank is Useless

I made a deposit of R1000.00 cash to my account at the ATM on Thursday, 28 March 2019 as I needed to make an EFT payment on 29 March 2019 for an order. I got a slip that showed that my deposit was accepted. On 29 March 2019 when I tried to make the payment, there was no money on my account. I phoned the branch and was informed that it shows at their side, but it is still pending. When I told them that I am not satisfied with the situation and needed the money, I was put through to the Manager. I spoke to a lady by the name of Julia and she took my details and said she will investigate the matter. Another lady phoned me back, saying I should come into the bank and lay a complaint and then they will take up the matter with the ATM people or who ever. I needed to make that order and payment today as this is the last day to do it. I am not satisfied as cash should be available immediately. Now I have to go into the bank on monthend and sort out a problem that I did not create.
