Wheres my airtime and data?

I previously recharged with R110 on 17/09/2015, and a 250MB data bundle as well shortly after. On 26/09/2015 I tried to make a call and was told to recharge my account.<br> I called the call centre today at 9:00 am approximately, to query it. I was told my phone used it all up. MY phone runs on Wifi at home and at work. I find it impossible that this could have happened now over the 3 years that I have been using the phone. It would have happened a long time ago if this was the case.<br> <br> <br> While I have a Contract number (which my wife uses) with the same complaint this week, Vodacom sorted it out within a day and gave me a complimentary 500mb just like that. - Thank you<br> <br> My question is why are prepaid subscribers being treated as a \lower class"than contract subscribers - and I am both. Contract subscribers complaints get sorted faster than prepaid and Prepaid are told \""theres nothing we can do\""<br> <br> Please just give me what is mine.<br> <br> Zeyn"""
