Upgrade problems

<p>My mother did her upgrade for new apple 7 plus at centurion on 5 November. There was no problem until 30 November when she was advised that an incorrect contract had been signed. Without any further communication or new contract being signed a new upgrade quotation was generated. She was advised on 31 December that the upgrade had been done successfully. However she was billed for over R2000 in December. Her account shows no upgrade on the contract but she is being billed for a new handset. She was informed via SMS that she had no data but her phone shows a balance of over 10 gig. She has phoned Vodacom repeatedly but gets no help. On Friday she was informed that her phone number is not on the Vodacom system, nor her id number and was then cut off. A very unhappy customer and wants to cancel her contract. </p>
