Vodacom is Not playing fair!

<p>For the last 3 months I have had a battle with the usage of my data. On the 1st of every moth I receive 5GIG of data which should last me at least half the month. By the 3rd I receive a vodacom notification that my data is finished. When I look at the usage meter I have not even began to use the data. In Oktober I bought 20GIG on the prompting of Vodacom messages that my data is finished of which all was only half or quarterly used. How on earth is this possible. Four days ago I bought 3GIG. This morning I had to purchase another 3 GIG after the notification was sent that my data was finished. Usage at that point was751MB wich I took a picture of. This is outrageous. It is like watching your pockets being picked, knowing who is pick pocketing you and you are absolutely helpless to do anything about it. On top of that I cannot for the life of me get any Cutomer Care because the have "High Call Volumes" and suggest I call back. Again totally OUTRAGEOUS!!!!</p> <p>How is it possible to loose data which you have not even used?? I would appreciate an explanation. </p>
