No response, no call back, unreliable.

I was told FNB would give me a call back with regards to an urgent matter. I did not recieved a call. This is after spending wasted time on the phone on a friend's overseas account, costing a fortune. They did not process my request but insisted on calling me back. I have sent an email to two different addresses every day since 2 December (a week ago) still with no response!!! Where are you FNB? How do you care for your customers? This is my third major issue with you and still no care to do anything about it? #cannotwaittochangebanks. I am waiting for your call or response in any form. Urgent! Please figure out the phone code, we discussed when I first phoned. 00972.
