There was a *****ulent cellphone account opened in my name with Vodacom which is not easy to understand as I had never done done anything with Vodacom. They than enlisted me with the credit bureau because of this *****ulent account which looks like an inside job. I followed their procedure of submitting the necessary documents when there is ***** and they told me that the account is closed. But when I am asking for a document confirming that the account has been closed They are taking me from piller to post. This has caused me a lot of hard as it has negatively affected my credit score
