Terrible service like before

Why am I not surprise that it is Nedbank AGAIN. My credit card account was settled and closed from my side, now after a month Nedbank has done nothing about closing the account on their side. This is impacting my credit record negatively because they haven’t updated the status on this account. Now after a month when I phone they have all sorts of excuses on why and that it is my responsibility not theirs, as if I work at Nedbank to have that authority.
