Vodacom allowing fruduelent accounts

I got a surprise call from Burnard Raaff on an outstanding account with Vodacom. I have never had a Vodacom account and up to this call I have never had any communication about an account from Vodacom.

If Vodacom is not able to properly verify subscribers it is a real reason for concern if anyone can easily sign up for a Vodacom service, rack up a large bill and Vodacom makes it the responsibility of an innocent party.

I have never heard of any similar issues with MTN
