Nedbank abusing clients

Mt wife and I had fixed deposits maturing on 18 April, 2019. Upon going into the website on 18th, we found that our cash was deposited into a "Justinvest" account and if we wanted the funds we needed to give 24 hours notice. We contacted the call centre who told us to go to the branch. As it was not possible as I was busy, I contacted the Nedbank complaints line. They told me that as I had given no instruction as to what should have been done with the funds, they did what they did. I was not given the courtesy of a telephone call or a text or anything. So I gave notice in 18th to have the funds released on 19th. So I find I cannot transfer all of it at once due to daily payment limits on my account. The call centre for small business was also not available today. So I will transfer the funds over three days, while Nedbank uses our funds interest-free. Hoping that the funds do move over the Easter weekend, but only time will tell. So our funds are effectively tied up over the Easter weekend by Nedbank,
