40GB?

<p>I converted Airtime to Data on my phone about 3x weeks ago and it was a sum of 40GB. Then on Monday my phone had a depleted data balance. How is this possible?? 40GB? Some companies cant even use 40GB. And I am sure that no one can prove or disprove any use of that my question is HOW IS THIS POSSIBLE? :( I phoned in to an agent on Monday and she was querying this and then it took me straight to your survey prompt (so I was cut off). Really upsets me. I've honestly through the years have been an advocate for Vodacom, but these past few months have found that this is not the case anymore. With so many competitors out there you would think the service would get better not worse :(</p>
