Experian Incompetency

I had an account with Vodacom that i have since settled beginning of 2021 and have the settlement letter. only to later discover that it's still reflecting on my profile as an active account. i disputed the account with Experian and sent them all the relevant documents and they responded after some time to say they've investigated and ruled in my favor. now months later when tried to get a bond, the Vodacom account is still reflecting on Experian and Vodacom has confirmed that i do not have any account with them presently and there's no way there should be an active account from them. Now why would Experian do an investigation and rule in my favor only to keep the record there and still list it as active????
