Nedbank and Attorney Erasmus

I have has a savings account with nedbank for nearly 20 years. I unfortunately lost my job over a year ago and went under debt review. There was a debit order going off my account monthly for the debt review however the last month my debit order went off my account while there were insufficient funds for the debit order to clear. My account is now in arrears. I have not heard from Nedbank themselves until I got an SMS today from Attorney Erasmus saying he can no longer delay the visit to serve the WOE? Firstly, how can this be the first contact i have received from them? Secondly, why am i not receiving email statements from Nedbank like i should be monthly? Thirdly, How can a debit order go through for payment putting my account in arrears when there was insufficient funds for it to clear? I never agreed to any over draft facilities?

I find this highly unprofessional and my opinion of nedbank has gone even lower than it was initially.
