Vodacom ITC Mistake (Second bad review)

This is my second bad review for Vodacom. So in June/July 2019, Vodacom incorrectly debited my account. The mistake was rectified by giving me credit. Skip forward to February 2020, Iv'e check my credit report and I see that Vodacom has not been updating my report. I called Vodacom and the Collections agent told me because payments haven't been going off my bank account, the my credit report has not been updated. If Vodacom debited my account correctly then I would have been able to pay my bank account. The Collections agent told me that because my account was credited, they will only be able to update my credit record after a few months. This issue is very unacceptable from Vodacom!!!! Vodacom needs rectify a mistake that THEY clearly caused.
