***** Not Taken Seriously at FNB

I received an SMS in the middle of the night saying my transaction had been declined because of using the wrong pin. I was not trying to transact then. I have tried repeatedly to call the ***** Line today and just had to hold on with no indication of how long I would have to wait. I didn't get through. I then called the FNB Care number which I had received in a response to my email to FNB Care. I was told I had called the wrong department and they couldn't assist me as they couldn't verify it was me. They then transferred me to the ***** Line and I had to hang up after a 3rd long wait as I need to do my work. The online App has not been working - I tried twice yesterday - so I could not check whether there had been any activity on my account after 30 September. What does one do with a bank which does not care about your account at all?
