Vodacom exposing personal information to another customer.

Vodacom has **********ly opened account on my details. I wrote a review 2 months ago on Hello Peter about this. They called and the consultant promised to cancel the contract because the statements they were sending me was for a certain customer who is in Mokopane and according to the law it is wrong because Vodacom is supposed to Protect personal information of their clients. Until today I am still getting phone calls from Mbd attorneys annoying me on when Am I paying the outstanding amount. Can Vodacom please settle this matter or it will be easier for me to consult the other customer to settle his payments with Voda so that they can stop abusing me.
