Ridiculous amount of money being debited off my account

<p>Since upgrading my contract I have had endless problems- ridiculous amounts of money is being debited off my account, almost quadruple of the amount I was informed it would cost. I asked to have a cheaper option and a top up contact (Which I have been buying airtime and data directly from my bank).</p> <p>Last night Vodacom debited R1500 off my account!!!!!!!!!!! HOW can you debit this amount from my account when I am on a top up and have purchased absolutly no airtime or data from Vodacom directly.</p> <p>I have made NUMEROUS phone calls in the past few months and NO ONE has gotten back to me. </p> <p>I require URGENT assistance</p>
