FNB Private Client Suite Disappointing

I am a private client at FNB and I have been a client at FNB for over 15 years now. I am extremely disappointed in the service. My private banker is never available and never answers the phone - on multiple cases where I have needed urgent assistance. I recently app**** for vehicle finance and FNB was not able to provide me with a preferential rate however another bank that I am not a client of has been able to provide me with a better rate? I do not see the Private Client Suite Services being offered to me at all! I believe I am paying a premium for nothing. It may be best for me to change banks as the service at FNB is appalling!!!
