Nedbank's huge hickup

From what I know banks are not supposed to make mistakes, banks are not entitled to make mistakes, banks should not make any mistake regarding their clients and customers information at all cost, because of its very sensetive, little did I know I was wrong, one of their employees hired by Nedbank incorrectly on purpose wrote my extremely vital and very sensetive information incorrectly and ooh well Nedbank is busy acting up here, and I can act up too and not taking this matter seriously, as serious as it is, probably they too bias coz of the color of my skin, based on my own private information that they themselves misrepresented, their own fault mind you, not even my fault, because of I'm certain they pressure and strain their employees to a point that it's hard for them to focus thoroughly and breath on a single client at a time because they so busy everywhere that they don't even pay attention to details, where as this is a clients information you incorrectly drafted and Nedbank you better sort this out soonest. What kind of a bank are you who makes this sort of mistakes, a whole bank that's as big as you, are you for being for real now? Huh 😡
