FNB Incompetence - No Working Bank Cards

So, my overdraft was eventually closed as requested. It took me complaining here for that to happen. When I asked to close the overdraft, I was told my account would change and a new card would be issued, and that someone would call me within 5 working days. That didn't happen, so I complained here. My overdraft was closed, and then they tried to call me for a card replacement for my account. The 2 calls came through when I was in meetings. I got an email after the first call, and explained that I was in a meeting, and gave a time when I would be available. She tried to call me again while I was in the middle.of another meeting. Then, she sent me an email saying that the case is closed because I have not answered my phone, and that she tried on numerous occasions to reach me. 2 times in one day, during meetings, when I responded with a suitable time is numerous attempts? My card is blocked now. I cannot use it to make any transactions. And, I am STILL waiting for my business account card to be replaced as well. My hands are tied. I have no working bank cards. How is this right? Why must it always come to me complaining here on Hello Peter for things to happen?
