Vodacoms horrible services

<p>I dont understand how I have already purchased 1Gig and had 300mb remaining but my airtime keeps getting less and less. Why but data if you just going to keep deducting from my airtime with NO notice.</p> <p>Lets not forget to mention mymeg. Won the 1gig for facebook, for games and for videos yet the data is taken from my balances and the 1 gig given to me for the day goes untouched. </p> <p> </p> <p>Whats the fineprint here?!</p> <p> </p>
