Appaling level of service and disrespect.

I am very disappointed because FNB doesn't take our complaints seriously. I am appalled with their level of service. Head office doesn't keep in contact with clients and also lie about their actions. Hello, is there anyone at FNB who cares about clients concerns? Is anyone out there? I normally get a quick response from RB Jacobs on Twitter. He asked me to wait for a day more to see if they actioned what they claimed to have done. I waited not just for one day, but 3 days later and still they haven't done it. Also he hasn't responded to my messages. I hope he is OK because he is very helpful and maybe he was unable to respond due to some serious challenge, but FNB head office should follow up on my concerns which are dragging on and one for ages! Very upset!
