Incorrect credit conduct submitted to credit bureaus

I have recently (December) taken a contract with Vodacom which is debited against my account. Vodacom have debited my account and even sent me a statement but they have the guts to report me being 2 months behind with Experian Credit and Transunion Credit Bureaus. I called them to rectify and the consultant promised to attend to this matter but until today nothing has been done.
