Complaint about vodacom

I have been incorrectly billed for something I did not use> Then because I was totally unaware that Vodacom has handed me over to the credit bureu

My acc reflects that I have miossed two payments of R31 I have been struggling to clear this mess up and finally got a letter from Vodacom on 1 Sep 2020 stating that Vodacom eknowledge their mistake and instructed the Credit bureu to rectify my records

As of to date nothing has been done to clear my name from a mistake on Vodacom side
