I'd like to see what "value packs" have been debited from, and possibly recredited to, my 2Degrees prepay account.

The 2Degrees Web site gives details of calls, SMS's, MMS's, data usage and top-ups but does not show purchase (or refund) of value packs.

My balance has been debited at least once (probably twice - an involved story for a small amount of $) for a text pack I never realised I had and certainly didn't want.  The most recent debit is supposed to have been reversed, but there's no easy way of determining whether it has been.

Is there a way of retrieving a detailed statement of cashflow of a prepay account?
