Vodacom - ********** Contracts on customer's name

In the past month, I have received the worst service from Vodacom. I have had a Vodacom contract for the past five years. Two months ago, I was billed for a contract that I have not signed up for. However this contract, was registered in my name, came with a new phone and all the additional services attached to the contract. I contacted Vodacom, and was advised to get an affidavit (stating this was not me) and submit this to them. Which I did and yet the matter is still unresolved. To add to that, I am still being billed this month for this new contract. Vodacom, clearly no longer requires a copy of your ID, Proof of address, or Bank statements when opening up a contract. What's worse, they cannot even provide information on where or how this contract was taken up. WHERE IS THE PRIVACY POLICY - WHERE IS THE PROTECTION OF CUSTOMER INFORMATION? What amazes me, is that Vodacom has not yet contacted me, regarding this issue. This is by far the worst experience I have had with a cellphone network in South Africa.
