Beware, nedbank loses your money

I was banking with nedbank for 40 years and have closed my credit card account. When speaking to a consultant, she confirmed there is a credit in my account and confirmed banking details to pay the money over. After 2 months nothing was paid so I contacted them again and was told the original consultant will phone me back which the never did. I then contacted nedbank complaints and was told they will look into it and came back saying the account is closed and there is a zero balance. So where has the money gone, I will be very worried banking further with nedbank if your money just goes missing. I then asked for them to go listen to the phone recording with no reply, I then sent another complaint and seem to just be ignored. It is disgusting that you trust a bank with your money and it then either gets ****** or just goes missing and then you just get ignored when you raise your concerns and want to know where your money is.
