FNB JuristicCRS spamming my mail and phone yet non-responsive

I no longer have any idea on how to proceed. They keep sending the same thing over and over. They require information for my business and continue to threaten freezing my account. This is despite having filled the forms and submitted. All information except a date field which does not update or even possible to type on their pdf based form. I have sent multiple emails and I keep getting the same automated response back - "Please fill in missing information". Complaining about the date being empty. I even took a small video trying to show them that their form does not work. I then realized by the nature of their responses that I was dealing with a machine. So I tried to call in. I was sent from one person after another. Eventually when I found a human being who was helpful, she told me I was not the only one. A lot of people had complained about the same form. I wonder why then FNB still sends out the same broken form, without testing and frustrating their own customers in the process. When she put me through to the JuristicCRS team, it rang and rang and rang until it disconnected. Luckily I had asked for their direct number upfront. I already have experience with this bank. I've been sitting on the phone for a long time a couple of times. Until I gave up. I do not know what to do now.

The sad thing is, looking into Hellopeter, I can see same issues dating back to 2020. Some even older. This is with regards to the same team, similar issue and same threatening messages. I feel like they are doing me a favor for the services which I pay for. My foot is already out the door and they just keep pushing. I pay for a private banker, but he/she is just as useless. No contact what soever. My wife and I app**** for a business home loan not so long ago. Her banker, also FNB, took over and guided her - I was shocked, because I do not expect that from them. A once off experience for me from them. Mine on the other hand, well, I was expecting it that they probably do not even know there was an application . Needless to say we did not even go with them because they can never beat any of the other banks in that department, in my experience anyway.

As for letting machines deal with communication, FNB is an example of how not to innovate (theirs is more like getting as far away from human touch as possible).

I still do not know how to make the spamming stop.
