Doing as they please in my Cheque Account

As your customer for so many years I feel it's time I take my personal account with another Bank other than you. This is not the first time this has been happening, taking amount as you please in my account. No notification or advise but because I bank with you and my Bond is with you, you do as you please. My debit order is on the 25th of Every month but the Bond account debit order has been just deducted without my authority in any way, the money that I have to spend with my kids for this long week end has just been deducted just like that, my salary is not even in the account. I called the Home loans department and I spoke to Peter who told me that payment will be deducted earlier if the day of your debit order falls on a holiday on which on this case it doesn't the 25 Sept is on Tuesday then why deduct 4 days earlier. I requested to speak to the Senior who said his name is Shama or Shamla who was just ridiculous had the wrong date even telling me that the 25th is on a Sunday not even sure which calendar he was using. The incompetence that I get from Nedbank Bond sales pple it's very painful and unbearable. Nedbank does send notifications should there be anything that customers need to be aware of but why DO AS YOU PLEASE ON YOUR CUSTOMERS ACCOUNTS. Is it because I bank with you, if was notified about the early debit order release I was gonna let you know about my salary only going in on Tuesday but NOOOOOO YOU DO AS YOU PLEASE IN MY CURRENT ACCOUNT. Please do not blame the system for anything as it is mostly controlled by Human Beings. I am sooooo disgusted.
