Airtime Disappearing

For over a decade, MTN has been my choice of network. Today, I'm not so sure. <br> So, I've been hearing stories about customers' airtime mysteriously disappearing. Well, it's been happening to me quite regularly, and it's no laughing matter. I hardly make calls from my phone, and use the wifi at work, so, airtime should last...guess what, it doesn't! You load R 100 and in the blink of an eye, it's all gone.. how on earth does that happen? Wednesday I loaded R 30,boom gone in an instant..last night I loaded another R30, and the same thing happened. When I called the call centre, they asked me to call back in 2 hours!! For what exactly? This morning I called again, and the lady told me there was a social update on my phone.. REALLY???<br> My phone doesn't do updates, unless I request an update on a particular app.<br> I think it's time to let my friends and family know that the stories are true. I think it's time to move to a different service provider. I'm so fed up! If they carry on doing whatever it is they're doing, they're gonna lose valuable customers, and I'm one of them!
