Worst customer service from FNB

I have been trying to call FNB with regards to the calculations of my settlement quote which I don't understand. I keep being transferred from person to person and no one is helping me or no one seems to have the answers to my misunderstanding. Its been about two weeks now trying to reach someone who can help me ,with fail. I have been calling and being told to hold and hold and the person that is handling my account is a no show for two weeks now .Its really frustrating cause I'm here busy spending my airtime on calls that never really solve my problems. When banks want something from you they harass you with calls and when you need answers from them, its always like this. FNB really is having the worst service when it comes to this regard.
