vodacom commits *****,

They changed my pre-paid number to a contract without my concent, I had a lot of problems to change it back. They still have not returned all of my talking points etc, and now Vodacom cuts me off if i phone them, and say that I have exceeded my calls to them. They also loaded my bank account with the debit order for the contract they put on my name. This was all done without my concent
