Vodacom treat you like a ******** even if you never had an account with them

Recieved my credit rapport today and out of the Blue Vodacom had listed me for an account in 2005. I did not had any Vodacom account EVER and was not even local in 2005. Phoned Vodahell and was passed from one dept to the next. Eventually the Legal dept tell me to prove to them I did not have an account? I ask for proof that I did had one and..... They put down the phone. Phone again ,ask for proof of acount and.... transfer me to a number that disconect. Phone again , get told again it is my duty to prove that I did not had an account ,not their duty to prove I had one and if I have issues go and log a complaint!!!!
