Reported to credit bureaus unwarranted

Vodacom reported me to all credit bureaus as being 30 days in arrears with my account, which is not the case. I want to apply for a mortgage, and this negatively affects my credit profile.

I reported the issue to Vodacom, who informed me that I need to write an email explaining the situation, and that, after they have corrected the issue, it will take up to 21 days for the change to reflect on my credit profile.

Vodacom, without any justification, reported me to the credit bureaus very swiftly, but are slow to fix their error, which I find unacceptable.

Your consultants don't have to contact me, just fix the error you created. I have written an email.
