Failure to act accordingly

I am disappointed with FNB my bank for so many years I've been with them. On the 30th of June i tried to withdraw money at Cosmo Mall but nothing came out. I logged a call with FNB and i was told FNB ATM Division cannot Assist me and i must go and open a case of ***** of-which i did but still the ***** department wont help me and its escalating the matter back to the ATM Division which failed to assist me in the beginning. It is very poignant get such a poor service from the bank where my salary has been deposited into my account every month for all this years and today FNB is failing me dismally therefor i am not happy with a lot running in my mind. All i need is to if FNB will ever help or i must just take my business somewhere else? I am not a treasury custodian of FNB and i don't even want to be one or Understand the process that FNB takes to make sure incidents like this do not recur again in future.

The are 2 options here: Either FNB resolves my Query OR let me take my Business somewhere else because i cannot stand for this ******** and humiliating service from the company I've had such a long wonderful relationship with.
