Not happy

In February 2025 I made a request through the fnb secure app to close my credit card. Was informed via the app by the consultant that my request has was granted and account is closed. In Novemeber on my credit report that I got from Experian the account is still there on an active status. I escalated to ***.i was sent a letter dated November that it is closed. Spoke to Shalini who confirmed the account was closed in February but the letter is dated to when it was sent to me. I then said I need answers because 9 months letter my account appears to be active still was sent an email saying the credit department advised that the credit berau keeps the account for longer. I am not buying this I sent the actual credit report and screen short from my Nedbank app where the account is still active on my profile.
