Nedbank Deceased Estates

I’ve had the unfortunate experience of using Nedbank to process my late mothers estate. It‘s a simple estate but it’s now almost 2 years later and no finalisation. It has been handled with disinterest and incompetence. This is the second time I’ve tried to resolve it through their internal complaints department but they do not even bother to respond. It’s difficult enough time losing a loved one but then to still deal with this is exasperating.
