I just realised I cant get history any more either. I think that this
is to make it harder for people to view over charging. I am regularly
over charged by Oyster especially when I use the more complex stations
like Waterloo or bank and the w/city line.

The web site is atrocious. They have gone out of their way to make it
difficult to navigate. Its a pity as the implementation of the system
itself was done so well.
