Urgent Request to Rectify Incorrect Arrears Status on Telkom Account

I lodged a dispute to have the Telkom account closed after it appeared on my profile, which Experian successfully addressed. However, they failed to update the arrears status. I’ve sent an email but have not received any response or feedback. In that email, I attached previous credit reports showing that the account was not listed, and for it to suddenly appear in June with 6 months of arrears doesn't make sense, as there was no record of it from January to May. Please rectify this error, as it has negatively impacted my credit score after all the effort I’ve put into maintaining it. Your prompt attention to this matter would be greatly appreciated
