I don't get what the big deal is. The rollover in my opinion isn't there for the constant user that doesn't use their bandwidth every month. The way i see it is should you maybe not use all your bandwidth in a month by some sheer miracle - it's cool, you can use it up next month. Following the industry standard of using last in first out, kinda sucks but we shouldn't be flaming them like they are the bad guys here...
Industry standard my arse.
Vodacom used to be FIFO as well until a while back.
It's a way of saying you have rollover without actually offering it. Marketing bull****.
