Airtime and Data just gone!!!!

<p>I have been a vodacom customer for years and normally when i'm about to run out of airtime or data, vodacom would send a sms informing me of this. So while wanting to go onto social media and after struggling, I decided to check my balance which to my surprise showed zero.</p> <p>On Monday 26th Decemeber i purchased a 500MB data bundle, this morning 30/12/2016 when wanting to use of my data my balance was on zero.</p> <p>I am not the only one experiencing this. My girlfriend complained of the same thing.</p> <p>This is totally unacceptable. Where has my data gone too???? I want answers</p>
