Will 2degrees give you a full bank-like statement of what charges/ credits have been applied to your prepay? It's extremely frusturating how vodafone/telecom force you to call their customer service to find out what a unexplained charge was or to see what something REALLY cost - it's clear they have a record of the charges, they just don't want to show their customers!
This would be a great way for 2degrees to differentiate themselves and be very easy/cheap to do.
