Customer Service

It seems almost impossible to get hold of an agent to assist with quiries. I've attempted a number of times to contact their call center and got cut off after 15 plus min of holding on. I want to know why my interest rate is STILL sitting on 22.25% on my overdraft when all my other accounts includig loans form other providers hve all come down as per regulations. Also why are payments taking so long to reflect in my account? Not to mention I did an inter transfer from my cheque to my credit card which took 2 days. WHY? I've been with FNB ever since I was able to open a bank account 27years to be exact. Think it's time to move on. Here I am yet again, been holding on for 13min and not even a voice ensuring me I'm #so and so in the queue. Frustrated is an understatement. My time and money is being wasted.
