Telecom really need to get this sorted. It shouldn't depend on which browser you are using, and there shouldn't need to be 3 different URLs you have to use depending on the circumstances.
2degrees Secure Portal always works faultlessly, letting you view all your calls (a first for prepaid mobile in NZ), topup with a credit card and more.
They are a much smaller company with revenues a tiny fraction of Telecom's.
If they can do it, why can't Telecom give us something that works???
It doesn't seem too much to ask really.
