No response on applications and calls cut off

I have now waited until 30 days to re apply for an increase of my overdraft limit and still no response from FNB when I apply.<br> <br> I tried to follow up by calling the premier banking suite but like before my calls get cut of or something goes wrong, and this now after I have been verified by the typing in of the last 6 digits of a card followed by its pin.<br> <br> FNB your client service is going to suffer severely if things keep on going like they are now.
