Current account debited before homeloan acc is due

I have been a Nedbank client for years. My homeloan and current account are with them. Collections debited my current account with R7935 before due date OR before the normal agreed debit order date. I NEVER AUTHOURISED NEDBANK TO TAKE MY MONEY. I GET PAID THE SAME DATE EVERY MONTH. How the hell, am I suppose to use the whole December holidays. <br> I do not earn a lot of money and the money in my account is for my December spent. Now what??? I didn't even get a notification that they are planning to take my money early.<br> Given the history, I even phone the call centre around the 17th or 18th of the month, to verify if they have not moved my debit order and I was told it remained unchanged.<br> What if I did not have enough funds??<br> I am sick of NEDBANK DOING AS THEY PLEASE ON MY CURRENT ACCOUNT, PERHAPS IT IS TIME TO MOVE MY ACCOUNT. <br> I WANT MONEY BACK TODAY AND I DO NOT WANT DOUBLE DEBITS. And I do not want double debits at month end due to YOUR INCOMPETENCY. I AM ON A HOLIDAY AND IU HAVE THINGS TO PAY AND BUY.. FIX THIS MESS NOW. Gloria (team leader collections) has a nasty habit of \making clients sound like they are retireds"& she imp**** that I was laying about the notification."""
