It makes me laugh that they couldn’t auto resolve this incomplete journey on Aug 5th, with a disabled railcard, surely this is not uncommon and easy to sort out:
0926 Waterloo Colonnade (LU)
0929 Waterloo LU/NR £2.05 charge
0935 No touch in to Bank, lets add on another £4.65
I was in zombie mode so forgot to tap the entrance to the Waterloo&City line thinking I had tapped in already. I will get onto them today but being an infrequent London visitor it is more complicated.
My other comment is that at the Colonnade entrance Waterloo&City is shown on the entrance but following signs to it not trivial at all.
