I got ****ed at the NEDBANK ATM when doing a deposit

Good Day to all Nedbank Directors Trust this mail finds you well. I am writing this email with great disappointment, frustration and heartache. Nedbank has showed me their system is very week and anybody can ***** their clients money. So people inside the bank can ***** our money. And all they can say is they sorry it will be investigated in 6 days. I don't have 6 days my mother can be in hospital dying and we can't live without food for 6 days. This is what happened. On Saturday, 28 October 2017. I went to the Glen Mall. I had R800.00 to deposit into my account as I don't like walking around with money as you all know how a person can be ****** in this country. So I went to the Nedbank ATM upstairs by the parking lot. I got to the ATM, put my card in, selected the deposit option, put in the money, the process was done, received a slip, card given back, and the ATM went back to its normal screen. I walked away from the ATM and went on to do my things. While I was at the shop I saw a sms says the R800 is deposit at 16h00 and a minute later 16h00 a reversed was done for the R800. I quickly ran back to the same ATM. But nothing look suspicious as there was even other people using it. That money might not be a lot for the bank but it is a lot for me. My mother is without medication she is a type 2 diabetic using insulin and we don't have food in the house due to Nedbank's negligence and week security. Nedbank I am not waiting 6 days I want my money now. My name is Jo ann Laing id no: ********** 087080
