Data keeps dissapearing a few seconds after I recharge!!

<p>So I've been buying data using my capitec prepaid option for the last few days.</p> <p> </p> <p>Everytime I recharge I get the following:</p> <p>Your Vodacom 1GB Once Off data bundle has been activated and is valid until 29/5/2017. To view balances, buy bundles & save dial *111# or visit vodacom.mobi</p> <p>Then a few secomds later:</p> <p> </p> <p>Your data on ********** 616 has run out. Out of bundle rates apply. Buy 50MB data to use in the next hour at R3 by dialling *124#. Offer valid today until 23:59</p> <p> </p> <p>I've bought a lot of data the past few days and I want you to sort this **** out now!</p> <p> </p> <p>Jessica</p>
