Not very helpful!

On the 1st October 2024 I was sent an SMS to say that I need to update my FICA information. I tried to see online what information was missing. I discovered that my postal and home addresses were in 2 different locations but the site would not let me change the one address that was wrong. I took time off work to go to the Bedfordview branch in Johannesburg. On arrival I was asked what service I was there for (to sort out FICA and to discuss an investment) I was then helped by someone that was not very informative or helpful. I was told that all they needed from me for the FICA was a copy of my ID, which I gave them. I mentioned the address needed changing but the person helping me just shrugged it aside as not being important. They also were not very informative with dealing with my investment query. I have now received another SMS (2.5months later) to say if I don't sort out my FICA, my account will be blocked. If the woman at the bank said that it was done, then why am I being threatened? Is it a **** or is the problem the wrong address? I am in my 70's and have been with Nedbank for 49 years- I don't feel respected in any way and will now have to take time off work once again to go and sort this out. One other thing I would like to mention - I am in my 70's, I have had a hip replacement and was made to stand at a counter where there was no chair and was not offered a chair - as I say, no respect or concern for an elderly long standing customer.
