DATA MISSING

<p>Hi I topped up with 20gb free me on Sunday afternoon. I checked my balanace yesterday and i had just over 1gb left. How on earth can 18 gb of data just dissapear. I use an old phone and updates are switched off. I call your call centre and wait for 45 min at a time only to be cut off. I am beyong angry and frustrated. I usually have data left over at the end of the month. Idont have another R599 to waste. I need this sorted out</p>
