Unauthorised Contract

...I was phoned Last week by a Telkom / CellDirect marketing agent as I was apparently illegible for an upgrade. The more I tell them we will go to the nearest Telkom, the more they pestered. This contract is in my brothers name and due to medical unfit declared I manage his finances, so this debit orders are being paid by me. They went along and did an upgrade and neither of us are aware of this upgrade. Today the courier comes to deliver Waybill ********** - returned by me as I'm unaware of this. I tried making contact but being cut off several times. This needs to be solved a.s.a.p. People need to know why we have the NCR in place in South Africa. People are bul**** into contracts.
