Vodacom handed me over to a collection company and I don't even have an account with them

I had app**** for a phone online last year with Vodacom under this reference number: ***, the phone was never delivered to me as promised and they went ahead and activated the SIM of the phone wherever it was. When I called to advise that I have not received the phone and I'm worried because I'm receiving notification that the SIM will be activated, I was informed by Rochelle Willemse and Asanda ***azi that this has been corrected and the application is canceled.

A few weeks ago, I received notification that my Vodacom account was handed over to MBD Attorneys. I don't have an account with Vodacom, the online application was canceled. Now I'm flooded with calls from MBD Attorneys asking me to pay an outstanding bill that I supposedly have with Vodacom.

I called their office, I sent emails and I'm not getting any joy, I'm sent from one department to the other and to make matters worse, I don't have a Vodacom number and it makes it difficult to get through to their Legal and/or collection unit
