Bad service from FNB

I am so defeated by FNB it's actually disheartening. I having been calling to be assisted with some account issues and I have not been able to win, from their chat services to all different numbers I was given and been asked to call desks I've already called multiple times with not help. Everyone listens and says 'please call this number I can't help with that'. I am feeling all drained now and helpless...
