Getting through to FNB is a nightmare!

Trying to get through to your call centre is a joke! You get a message stating high call volumes which already tells you that you are going to have a miserable experience on the call. Then I get through and ask for Overdrafts and get through to every credit department but overdrafts!!!! Your staff don't know what they are doing on the phone but it's like they are there just to keep us busy going through from one automated system to the next! All I want to know is why I did not get my debit interest rebate this month, one question but taken me over 3 days (I tried on Saturday too) but no answer yet! Also RBJacobs on Twitter just answers those he feels are good enough for responses which wasn't me.
