*****ing money and continuously subscribing

<p>For the last week I have been getting an SMS saying</p> <p> </p> <p>"Welcome to Vodacom airG! First day FREE then R2/day. Click here to continue: [link] or Click here to Unsubscribe http://live.vodafone.com/unsub"</p> <p> </p> <p>Each time I receive it money is taken off my account. I have unsubscribed 4 times and I am still getting this SMS.</p> <p> </p> <p>I refuse to pay for services I have not signed up for and don't want.</p>
