Debits after contract is cancelled

<p>I cancelled one of my Vodacom contracts after the contract expired over 2 months ago. Ofcourse it was not actually cancelled on their side, and they continued to debit my account (but for some reason at the original contract price before Vodacom decided to do the shady in-contract price increases). And, although I wanted the contract cancelled and I am not using the device or data, they would not refund me, for their mistake! Ridiculous.</p>
