Terrible just terrible

Here we are again…my Fusion account has been settled in May of 2022 it has been closed in October 2022. Till date after asking so many times, been pushed from the branch to the call centres multiple times, this account is still reflecting on my credit record till date as in arrears, yet it has been closed, I have been told multiple times that they would update it on Experian credit check but it is still there. I have asked for the closure letter to be sent to me multiple times, not just with my account number but my card number too as this is what is showing on Experian but still nothing. I am so fed up with FNB so so fed up
