airtime loaded and vanished all in one go.

My airtime and bundles (R420 and 150mb data) all gone within minutes. I do the same activities every morning. What takes less than R5 everyday took all of this today. Ive called the call centre twice and no help at all.<br> <br> I cant be expected to keep making mtn rich while the **** us of our airtime time and time again. This is not the first incident like this. Ive bought airtime that vanished before an sms could come in before. <br> <br> Im always connected to wifi so updates only happen then. Im really annoyed at this point at the frequency of this.
