FNB - No help building my life or my business

FNB makes a lot of promises but doesn't fulfil. All the adverts about looking after their customers and taking care of you even when you are having difficulties is a lie. I had a problem 15 years ago when I was blacklisted due to a divorce. I am a single mom to 3 children whom I fully support. I am a medical professional and have a PhD. I only opened my bank account with them 8 years ago when I opened my practice. All sorted and cleared about 4-5 years now. I am a private client, have significant funds coming in, no credit bureau issues and still get declined. They wont give me a credit card. I had to apply to Nedbank who gave me one with a great limit. I had 4 devices on my profile, as I supposedly as a Private Client qualify for this. No defaults in the past 3-4 years. When the last one was paid off I went in to get another for my daughter- they declined me. I am a Private Client- what does that mean if I am treated like a non-entity. In the past year my private banker has been changed 4 times- unacceptable. This bank lets me down all the time- no special nothing. I am so saddened by who they are and what they stand for- just making profits off me and my kids..FNB no help to us!!
