Over draft facilities

I have been having a overdraft of R10K with this bank and my salary has been going through them for the past 3years+ till to date. Apparently I over spent that R10k nd I was taken to the legal department and my account was frozen after my salary got through on Friday the 24th and I approached my nearest branch in brits. Only to find out that the overdraft facility was taken from my salary and I cnt access it again and my account needs to be closed immediately. I was not notified and also I can't survive with out this money. Atleast if they had taken 50% of the overdraft out of my salary so I can survive because now I have no money nd cnt live like this. I've been a loyal client to nedbank but what is done is very ********* them knowing my salary goes through to them. Nedbank please access me at least R7000 nd take the overdraft back every month with R3000. How am I going or suppose to survive?
