Complaint

I've been harassed by phone calls from MBD since August, stating that I'm owing a Vodacom account that I know nothing about. Today when I was checking my credit profile on clear score, this "so called account" is added on my profile and it says I opened an account in April this year. I never had an account with Vodacom or used a Vodacom network in my life. Please assist because this is good to ruin my credit profile.
