FNB won't assist

I requested a settlement amount on my FNB Gold Credit Card on 09/02/2022. I settle this the following day 10/02/2022, I send the Proof of Payment and a Closure Letter is then sent to me. My husband and I are applying for a home loan, I receive my credit report.. 07/04/2022 Only to find that the Credit Card is still open and active this reflects negatively on my affordability and who knows what else.

I was just told by a rude consultant that: "On your transunion report it will still remain as an open account though with a R0.00 balance and R0.00 instalment due. The actual update of the account usually take no more than 21 working days. if the data apprears as incorrect, you are ecouraged to dispute the account on Transunion, transunion will refer the matter to FNB and FNB will confirm closure."

So what this consultant just told me is that FNB did not do their job and now I have to do it for them. This does not only show on Transunion but on Experian as well.

I do not owe FNB anything and all I want is this updated on my credit record! FNB was a good bank, it has completely gone to ****.
