<p>This is the second time this year on a public holiday vodacom made my airtime disappearof which is not good or fair, actually its kind of annoying I know that my balance was R217 or soo but suddently I have R0.00 I made only one call of which was not picked up. I don't like it at all it been a years iv've been using vodavom but now I am not happy at all that I will keep calling or writing about vodacom if its not Data its Airtime what the hell I want my airtime back as I want it back I work hard for the money I spend to but airtime, its seems as if every public holiday they think of *****ing airtime or data from customers I hate it. I want my airtime back as sooner as possible it has become a habit to vodacom a tiring habit. I want my airtiem shame vodacom.</p>
