Data bundle and airtime gone AGAIN

<p>So this is the second time this has happened, first was about 2 months back. I bought a 1gig 7day bundle on 05/06/2017 at 21:02 valid till midnight on 11/06/2017. I was away from home for the week so I used that data to stream, browse etc. The next morning at 7:18 on 12/06/2017 I bought a 1gig 14day bundle which expires on 25/06/2017 because I'm back home and have wifi so my bundle would last. This morning to my surprise I get a notification saying I ran out of airtime. My data is 0mb and my airtime is R1.... Called the call centre and get told the last thing they can see is my 1gig purchase on 05/06/2017. Sort this out because this is unacceptable, How am I suppose to make calls now during the day if I need to? Should I buy MORE Airtime for my Contract? Totally ****ED off right now</p>
