Disappointed and Disgusted with FNB's incompetence

We have been loyal FNB customers for almost 10 years now. Recently my husband's boss paid his money in on the 8th and usually it would be in 1 -2 working days that it reflects, but this time it took more than that. Now we are stressing because our medical aid has been suspended, we borrowed money for food and our other bills, so it's been chaos s****ing by. We went to FNB to ask them if they can see what is going on, eventually they told us after referring us from 1 person to the next, that it can take up to 5 working days. That's all and well, but it has NEVER taken that long in the 10 years that we have been receiving a salary. So we wait the 5 working days and still NOTHING. We go back to FNB on Monday 14 May (had to get off from work to do this every time) and the consultant gave us same story - "please just be patient". Eventually my husband got irritated with the incompetence and he told them he is not leaving util they properly check what has been going on. So EVENTUALLY they inform him that the FNB banking has been hacked (15 000 people or so) and that his account was one of them so they temporarily locked it. As per usual "we are sorry for the inconvenience" and told us it will take another 10 working days. My husband explained to them, we are at a point where we cannot buy food and if something happens to our children, we are not covered! They then explained to us that we should have our money by Friday, 18 May (today), so here we are STILL NO SALARY. I can honestly not express my disappointment and disgust in their service. We have two small children, we need to get to work and they cannot even slightly accommodate their clients who have to suffer at their mistakes or problems. I feel for a bank that constantly advertises - "how can we help you?" they DO NOT HELP AT ALL!
