FNB RUN AROUND AND NO ANSWERS

I am deeply disturbed by the lack of knowledge as well as empathy that FNB has shown us. My Father passed away, we let the bank know of this however when we went to attend to his Estate, the bank had not closed or frozen the accounts and let charges incur. When we went to the bank, we were told to call a number, I did this, only to be told it was the incorrect number. A new number was given I called the number and after holding on for over 10 min, and speaking to various people, another agent finally answered who appeared to be in the correct department. Once i told her my situation, she put me on mute and waited for me to put the phone down. This was the 7th person I had spoken to. I again tried to call and never got to speak to an agent again. My Fathers accounts are not seen to and I am still not any closer to having anything sorted out on my late fathers banking affairs. This makes and already sad and unpleasant situation just worse.
