Nedbank I want my money NOW!!!!

I'm extremely appalled by your service. I did a send iMali transaction to myself due to security reasons. I was standing in front of the ATM when I got the OTP, and the ATM says it expired. I tried again and it said the same thing. I thought maybe it was the ATM This was on Tuesday from 19h22pm I tried again at a different ATM at a different area. Even then I was standing in front of the ATM and it said the OTP expired. I left it because clearly your stupid system had issues. I was on a chat with an agent yesterday who said it was a technical issue with the send iMali function and it will reverse back to my account. Today is 48 hours and I even have smses to say the money will be reversed to the sender. I checked my account and the money is not there.I started another chat today trying to find out what was going on and Carl Sauls tells me that it takes 48 hours to reverse AND it will take another two working days to reflect in my account I find that extremely unacceptable and for the different information I'm told and I have to suffer the consequences of your technical issues. I need that R800 yesterday and all I get is a stupid "I'm sorry for the inconvenience" I will not accept that. I want my money now or close all my accounts with you
