Lack of update

I have been waiting for FNB to update me on the status of my complain, however it has three days now and each time I call in the consultants don't want to connect me with the supervisor and when I persists they hang up on me- I believe it is FNB POLICY to deny customers the right to speak truth to power! I am helpless and frustrate,does one need to be pushed to resort to violence to get the matter resolved?!
