Vodacom not updating credit profile whilst receiving my debit order payment without fail?

I have been a customer of Vodacom for many years, not missing payments and have a clean overall credit profile with no missed payments in 5 years. In February 2025 a missed payment was noted on my ITC and Experian credit profiles. The money was taken from my account, it was not missed. I phoned Vodacom 3x times over the past 2 + months spending significant time on the phone. In all instances the agent confirmed there was no missed payments and that an internal instruction will be sent that my credit profile will be updated. My monthly Vodacom statement received shows no missed payment either. This has still not happened. On the first call the agent did call me back a few days later. No return after call after that. Called again, established the same that there was no missed payments and the profile will be updated. No call back, no update of the profile to date. The negative score on my credit profiles remains and affects my application for vehicle finance and other facilities. How to resolve this?
