Absolutely pathetic and distrustful client service

Worst client service ever, you can't complaint about the service because there aren't any. Staff inside the bank are willing to help, but it seems that it's out of their hands as well because their head office is dysfunctional. I have opened an estate account on the 25th of November 2020 at FNB bank and asked Nedbank to close my late mother’s account and transfer the funds over to the estate account at FNB. I was promised that they will look into it and get back to me with in the normal 7-14 days and they would keep me posted. I was told in the bank that there were several procedures to be followed for it to be finalized therefore I accepted the bank’s regulations and did not have any problem with it as it was the prescribed process. Since then I had to out of my own followed up with the bank on what has been done and how far the finalization is. We have only received feedback via email from the bank manager on the 15th of January 2021, more than a Month later. Now we’re on the 20th of January 2021, and still no further notification on the progress. How do they expect a client to put trust into them with their finances? If I were a Nedbank client how do they expect me to put trust into them with such poor service, is your money going to be safe with them? The banks were not closed over the Covid period, they are using this as an excuse. This is absolutely unacceptable. Your communication sucks!!!! What the hell? Finalization is long overdue, don't you think!!!!
