I have been a client at FNB for many years

I have been a client at FNB for many years. I was at two branches today in Pretoria FNB Lynnwood and FNB Hillcrest Boulevard with a query. The worst service ever from a Bank. I waited 45 minutes in FNB Lynnwood inside The Grove mall, the call center never answered the call. The same story at FNB Hillcrest Boulevard. I will be changing banks. They get a zero rating from me for service. I am ****ed off with FNB
