Vodacom Theft

<p>I can't understand why Vodacom cannot carry over my unused contract minutes onto a pay as you go account (also with Vodacom) I have fulfilled all my requirements in terms of contract time and monthly debits, however I still have some minutes left over which in all fairness I have paid for but not used. I was told that those minutes are forfeited but a forfeit is a penalty for wrong doing. What have I done wrong? Those minutes have been paid for and I'm entitled to use them. Surely it's not so difficult to load my pay as you go account with the remaining minutes??</p>
