I would like to complain about:

(a) The unavailability of a Super Off Peak fare on a journey Fleet-
Clapham Jn-Shepherds Bush

(b) The inability to buy a ticket with Network Card discount from a LU
ticket office. This was a real pain on Monday on my way back from
Brussels. If they can sell tickets with NR components, why can't they
apply NR discounts?

Anyway: whom do I complain to?
