Vodacom - Request to Convert Number from Prepaid to Contract

<p>I have logged a request online with vodacom to convert my current number from prepaid to contract. I clearly stated that Convert my current number from Prepaid to contract. They told me as soon as the phone comes i must call the activation department to activate and they said they will give me a new sim card which i must not use until they activate it. As soon as i received the phone i called the activation department and they told me activation takes about 48hrs and i must not use the new SIM until then. After 48hours i called them and they told me my contract is already activated with a new number and there is nothing i can do because they are using a new system which automatically assigns new number and now i am stuck with a number i dont want and on their website they still give this option which is not available.</p>
