Experian is not updating my credit profile

Experian is not updating my credit profile. I submitted a dispute on 19 December 2023 about an account that was listed as a default and removed after a year. The account(Standard Bank) is back on my profile, showing to be nine months in arrears. Teljoy account paid up and closed in 2022 still showing on my profile as one month in arrears. Contempo account that was paid up and closed in 2019 shows that its one month in arrears. My life is one stand still because of Experian. They have an exclusive relationship with my bank and I'm just wasting my money on a private account because Experian is shows im a bad payer. Everything is fine on the other credit bureau but Experian. Help me.
