Penalizing users due to fault from Vodacom

When applying for credit a decade ago, an old Vodacom number was linked to my credit record and I was declined. After discussions with Vodacom and them accepting they never removed a settled account from my name, this was removed form my name. I now get declined by Vodacom, ten years later, for fiber at my home, because this old query is still active on my name. They will now remove it as this is settled and they do not know how this is still against my name. They declined me a service because of a fault they made, after numerous phone calls I had to make to try and establish their reasons for declining me the service. And even after admitting their mistake, the operator has a no-care attitude that I can re-apply after 24 hours.
