Contract cancellation - sending me from pillar to post

<p>I cancelled my Smart S contract with Vodacom in July and upgraded to a 1Gig contract. To date the Smart S contract has not not been cancelled and my data contract is not effective. What annoys me the most is that they are charging me for the contract I cancelled in July.</p> <p>When making calls I'm sent from pillar to post because no one seems to know what to do. I'm tired of this pathetic, appalling service!!!</p>
