FNB - Where Clients don't matter!

I have been a loyal FNB client for many years but FNB has changed their valued customer focus. I have made two attempts at getting FNB to sort out a problem I have been having. I continually receive automated responses which affirms a dispute reference number and that I can await a call within 48 hours. It has been two weeks with no response from them. Service delivery is not their priority.
