why are transunion balance not correct or account updated closed when paid up??? 30days later

i closed my fusion account december 2024 (paid up in full) and downgraded my account to an easy account. However im told they cannot remove that record on transunion because there is no trace of that account???? How is that possible that you can update when account is not paid or something and the balance is ever inccorrect. i have complained twice at fnb no help. this account was closed 14 December yet its still active and owning at transunion? can someone please update and remove that account from my profile. my ref for fnb query is ***F. im tired of waiting for complaints to get back to me 10days later now and a month after i closed that account. dont call me send emails to resolve this to keep record
