Trying to cancel Vodafone contact

<p> Iam trying to cancel my vodacom contract as it expires at the end of November. Every time I call in I either get transferred to the cancellation department an hold on for over 20 minutes. It's like they purposely want me not to cancel my contract. Either way it looks like I have to pay an extra month for absolutely nothing. They so quick to sign you up for a new contract but when it's time to end the contract you it issues. They even gave me 2 free minutes for the all the times I have called into the call centre the calls was dropped.</p>
