Missing Data

I've had a Top up data contract with Vodacom for the past 2 years. This month I went to the vodacom store in Rosebank and requested to be reverted back to prepaid when my contract ends on 29 February, only to wake up this morning and data that I had topped up days ago, gone from my phone. I called the call centre to ask that they reallocate my balances, a Lerato Khonkhe told me that someone was \supposed\" to tell me that when I move I forfeit data that I bought with my money and there is pretty much nothing I can do about that. It's disgusting how Vodacom is ripping people off. Your customer service is pathetic, after I've been a customer for over 12 years. When you delete almost 2 gigs of my data, the best you can do is say you're sorry? Pathetic."
