Nedbank *********** and rude.

2 weeks waiting to get info about fixed deposit details. A whole lot of useless emails and when I finally complain, I get an unhelpful email addressed to Mr Nyirongo. I have no idea who he is, certainly not me. How rude. So I phone 'complaints' and am assured a manager will call me about this whole debacle. No one does so I phone again. Am told the same thing, and still no one phones. Why do I bother?
