Dissapearing airtime

<p>Come on Vodacom. This is highway *******. Again load airtime. No calls, no sms, no data usage on any media and its all gone. I got a call last time saying its my dropbox thats eating the airtime. My phone does not have drop box. I have deleted all running services. Nadda!!!!</p> <p> </p> <p>So i ask now, where does the airtime go to???????</p> <p> </p> <p>Thinking of porting to MTN. Maybe i will have better service and wont get ****** everytime i put airtime.</p> <p> </p> <p>Regards,</p> <p> </p> <p>Tyron</p> <p> ********** 462</p>
