Fnb Private clients no service

In March 2024 i app**** for a credit card limit increase,to which FNB responded that i qualify to become a private clients account holder meaning illbe upgrading from my Premier Fusion account(what a mistake). After i told my "newly appointed private banker and his manager" that i wish not to as i am also not sure i will be able to afford the monthly account fees going from R230pm to R420pm. I was told that they are running a promotion which will have me paying Premier fusion fees R230pm for 3 months to let me decide whether i want the private clients account or not. Well here is where all my trouble started when i said yes,my first issue appeared 2 days later after i made a purchase on my credit card on budget facility only to find out it was put on straight facility, so i tried phoning my "private banker" with no success i eventually phoned private clients and got hold of someone else who helped me. After that every month when it came to my account fees the full amount of R420 was deducted instead of R230 as discussed amd everytime i tried to phone my private banker or his manager their phones were off or said it does not exist so i requested a new private banker assigned to me(no success) on the 1st of June 2024 same story happened i phoned private clients again from the Carnival mall branch and the advisor i spoke to told me on the system it says the client must be educated(im a child it seems) that it is the account fees and cannot be reversed. I asked him to contact my bankers manager as i want to speak to her,i got told he does not even find such a person on the system (10min later he did but still no luck) so i requested for another private banker to be assigned for the 2nd time it is 2 weeks today since i spoke to him and no one has contacted me or even my current banker to discuss the situation. I have also requested to move my account back to premier fusion when i got told sorry you can't. This is absolutelty the worst service i have ever had from any bank
