Account closed and no communication from Nedbank

I went to the ATM today and the ATM swallowed my card and instructed to contact the branch. I had to drive to the branch only to be told that the account had been closed from CCM side (Credit Management). When the client services lady contacted CCM they informed her that the account was closed due to the account being in a minus. they stated that they had tried to call me but didn't get hold of me. Let me make this very clear. No one has called me, I have not received any communication to the fact neither but email, telephone call, post or sms. How can they just do that. They have now informed me that I will only be able to go in tomorrow to the branch and I have to open a new account. I called Mabaseka myself from the office and she just hung up on me. What a HUGE hassle that is going to be. Due to their incompetence I have to not only open up a new account but also inform all of my debtors about the change as well as moving all of my debit orders and reloading my accounts that I pay manually. If I had know that Nedbank would be this *********** I would never ever have move to this bank.... Everyone Please Beware
