Tired of this bank's bad service

I have been with FNB for more than 10 years after moving from STD bank, I feel that I have overstayed as a result I will be moving my account to a bank that will treat me with respect and remember that customer is king, I have leant about my arears of my home loan account in December subsequently I am expected to make a full payment within 2 months. 3 months ago I app**** for a home loan access as was I expecting a huge some of money and still to date that hasn't happened, If that was opened most probably I wouldn't have found myself in this situation whereby I have be called by their nasty consultants who speak to one like dirt. Instead a wrong account was opened on our behalf and no one is addressing, I am so disappointed and angry especially with the last consultants who spoke to me as if I am an illiterate and one could tell that she was enjoying herself instead of trying to understand where I come from. I have been assigned a private banker why is she not the one to call instead f this *********** consultants. I feel that the time has come to part ways with FNB and I will be looking for a bank that can suit my needs and moreover treat me with more dignity.
