Putrid service from Nedbank

I was just called by a lady by the name of Angie with regards to my overdrawn account that I had requested for the closure of in January already. I tried explaining to this woman that my case is currently being attended to by the branch manager in the greenacres branch in Port Elizabeth and that she would be the best person to speak to. At the moment I'm in a conference and unable to access my work emails so I explained to her that I completed a form and sent it to the branch manager. She became so rude and told me that they would keep calling me until I pay the overdrawn amount. I feel so harassed and disrespected right now and demand that this issue be addressed. At this point I am so happy to have migrated to FNB.
