Vodacom unable to tell me where 900MBs went in a matter of minutes

<p>I recharged my cellphone with 250MB of data, only to receive a text within minutes that my bundle had been depleted. I urgently needed data so repeated the process of buying data, only to have the same thing happen again AND THEN AGAIN! I phoned Vodacom twice and sat on the phone for 15 minutes each time but nobody could tell me where my data had gone! I wasted R180 on data that simply disappeared, Vodacom took my money and couldn't offer and reasonable explanation. Very unhappy customer! </p>
