Correct my profile

I was handed over during covid to VVM by vodacom for my account as i could no longer afford it. i was paying VVM directly and had nothing to do with Vodacom. No one was updating my profile (credit) that i was paying off and left it as a default and nothing paid and kept showing the original amount which is not fair as i was paying it.

now that its paid off NO ONE will update my credit record, not vodacom, not vvm and each of them send me back to the other. i want this sorted and cleared I am not able to apply for finance of ANY kind due to this!
