4 years and still incorrect data

I went on the My Vodacom site and logged on and after nearly 4 years of being a customer and being a Red Advantage Client and paying thousand of Rands a month - the previous persons name is still on the system with his e-mail address! Pity you not debiting his account either!<br> I then call the customer care centre and was told to go to a store to change the details? When I took out the contract it was telephonic? when I renewed it - it was telephonic - now to change my own details - i cannot have it done by a customer care representative. I am a couple of weeks away from upgrading - maybe I should rethink my service provider.
