Sheer disregard! Not putting me FIRST

FNB ***** Department- slow to no response on what is happening or how to resolve a matter. Recently my accounts have been frozen for 28 days and no one from FNB called to notify nor indicate the nature or why. I had to do my own inquire and was guided by an call centre agent what to do. My annoyance is that I'm not getting clarity nor direction on how or what is happening. I have been implicated in a **** and I was not aware not did my banking institute inform me as to the nature and severity of my accounts being frozen. What would have happened if I had an emergency and I could not access my funds. Im aware that I can still deposit and receive payments in my account but just not withdraw. What is the hold or waiting period from FNB on one's account? Why has no one called nor attempted to reach me the client as to the above regard?
