Debiting for a subscription service I never signed up for and after I had cancelled my contract

<p>Disgusting service! I cancelled my vodacom contract and was told all was in order, last month R800 + taken off my account and I made contact and was told it was for data usage.</p> <p>How can it be data usage when the phone was off and in my drawer! Then this month R1400 taken off now its for a subscription that I never subscribed to!</p> <p>Vodacom you need to get your act together, one more debit off my account and I will sue you for *****!</p> <p>Account I***</p>
