Fed up with FNB's horrible client service

If I could rate lower I would: I have both my personal and business accounts with FNB. I have recently (since Thursday) tried to open an overdraft on my business account to no avail. 1) I have tried the online application - filled in a form, got my email with ref number that stated I will be phoned within 2 business days and nothing happened after that. 2) I have tried the call center - I had to hold on for 25minutes to get through to a lady that said she is not able to help me another person will phone me back after she did the security checks and everything. Got cleared she promised they will phone me back before the end of the day.... 2 working days (and a whole weekend) later NOTHING??? 3) I went to the bank on Sunday and a lady told me that she can not help me nor can anybody at the bank - I have to wait till Monday when there will me a business manager at the bank tha can help me on Monday. I went on Monday and guess what? I was told once again after waiting 20 minutes of my precious busy working schedule that once again I CANNOT BE HELPED AT THE BANK and that I have to wait once again on a different day when somebody else is there. 4) I told this last lady that that is the worst service ever and she said that I can email a specific person about said problem and they will help me within 30minutes. I took the email address and went back to manage my sites as I can not leave my guys for too long alone. When I got there I sent an email to the said email address and guess what? I got a return email stating that the email address DOES NOT EXIST????

I am fed up that I have to struggle my ass off just to be able to do something extremely basic at a supposed to be awesome bank. How do we resolve this? Do I approach Capitec or Nedbank or somebody else and hope that they can deliver service to their customers?
