Vodacom Contracts cheat us

<p>1. My mom and I took contract phones for the amount of R420pm and now her debit order is R600pm.</p> <p>2. I had +-R80 airtime and purchased 100MB 1 day data this morning and when I checked my balance later, I had R2 left!!!</p> <p>When I called customer service they couldn't explain what happened to my airtime. </p> <p>They claim that I didn't purchase data but how come I got a notification saying that my 1 day data expires 02/08/2016 at 23:59???</p> <p> </p> <p>I'm very disappointed.</p>
