Premature cancellation of Vodacom contract

My contract is due for upgrade and I was informed by Vodacom that I can only cancel my contract after the 25th March 2016. I requested a Premature cancellation of the contract meaning before the March 25th date.<br> <br> A quote was sent with no amount to pay and I was promised that the contract and the number will be cancelled and deleted within 24 hours. On the 22nd of February I called Vodacom to ask why the number was not cancelled and I was offered a cheaper upgrade and I refused and another cancellation form was sent.<br> <br> I ask the agent how many forms should I complete just to cancel this contract.<br> <br> I called again this morning and was assisted by a rude agent by the name of Megan who offered me an upgrade on my contract whilst I made it clear that I wasn't interested in his R110 p/m contract. I requested to speak to his Manager/Supervisor and he refused saying they are all in the meeting for the whole day. I requested a reference number for the call and he refused to issue me with one.He then put the phone down <br> <br> I only need one thing from Vodacom, to cancel the contract as I have signed their Premature Cancellation and they must stop offering me an upgrade I am not interested.
