Airtime expired before it was supposed to. Basically theft since I paid for it.

I need someone to assist me urgently. My monthly airtime allocation has been completely removed before it was supposed to be. When I went to bed I haf R117 airtime. How on Earth do I wake up to R2 airtime?

I call customer service and I'm rerouted to cancellations. I speak to a consultant who says there's nothing he can do a call will be logged. I'm yet to receive any reference for this. So I called back and a different cancellations consultant says I should speak to customer service. At this point I realised this isn't going anywhere. Why do I have to make a public complaint for a simple query to be attended to with respect and courtesy. I really don't get it.
