Such a disappointment

I am a Premier client and I am in the process of buying a vehicle for my wife. I decided to make use of my so called "Premier services" if you can call that service. I phoned them to assist me with my application as FNB website states that PREMIER AND PRIVATE clients can apply through their banker (https://www.fnb.co.za/vehicle-finance/dealership-finance.html). So...as I called the first time to ask for help I was told that it is only for PRIVATE bankers, which lead to my question why FNB website states it is for PREMIER AND PRIVATE...no explanation given, just that it is only for PRIVATE clients....my next question was why it was stated that it was for both?...no answer, just again that it is only for PRIVATE clients. I accepted that I was not going to get any where and asked them to put me through to FNB Vehicle Finance...the phone was dropped in my ears, not once, but twice. After my 3rd attempt I asked for a supervisor and was kept on the line for more than 5 minutes without any feedback or assistance. I have always received great service from FNB (my bank) but this was frustrating and annoying as it felt like my days at my previous bank that made me leave them for FNB. I am not above anyone or entitled to be handled specially, but at least to be treated in a professional, fair and decent matter and according to your website that states PREMIER and PRIVATE. Thanks so far for all the other good service received.
