Data *******

I am constantly querying the data usage on one of my lines with Vodacom. 5gigs of data was used from 1june to 8 June...FIVE GIGS!!! Vodacom can't give me a proper explanation of why??? <br> Then last night I had 100mbs plus R50 airtime. They first used all my airtime and 80gigs of data. I only had 20mbs of data this morning.<br> Why was my airtime used first??? No Vodacom can't explain.<br> The call centre agent 'advised' that I put off th cellular data when I sleep...great advice! Why do u sell me a smart phone that I can't actually use!!!<br> I've always been a Vodacom customer....but they very quick to take your money but can't really help u when u need it. I am really considering moving my four accounts to another service provider.
