Nonsense service nedbank

Guys nedbank is just a nonsense bank, I had a credit card with nedbank, then I phoned in to get settlement amount so that I can pay it off, I did that successfully, I paid my credit card finish and I phoned to request a paid up letter which I was promised it's going to be sent to my email address which never happened, the worse part is for nedbank to never update my status on my itc record, on all credit bureaus my name appears as if I still owe nedbank credit card, please tell me what the hell must I do in order for you to take me serious? I am now applying for credits in other places I am being declined because of nedbank still appears as active, I am taking you to hello Peter and I am involving my FNB lawyers if this is not being sorted out by this week. I promise I will fight as big as you are, if need be eff will be involved in this nonsense, I will definitely ask them to assist me in suing you as big as you are I am sick and tired of your incompetibility this is nonsense sort this nonsense out clear my name on compuscan, Xperian, transunion and the other credit bureaus and send me the stupid paid up letter for that nonsense credit card.
