Struggling with transaction sms'es for over a year

And once again money is gone from my account without me receiving any sms on transactions. This time for over R600. I am sooo fed up complaining about this problem- I've been struggling for over a year. Can some one from this completely useless bank please contact me, tell me where my money has gone to, tell me how many years of my life I will be waiting for your to pull up your socks to actually do as promised, and also inform me what it will cost me to close all my accounts at Nedbank - so I can bill you for it - as Nedbank is forcing me to move because of sad, sad, sad bad service! I do not even have the strength to fight any more.
