So what did you do?

Got it exchanged for the correct ticket at Liverpool Street, who sighed
sympathetically, as the clerk at the station in question was completely
clueless, to the extent that I got a letter from WAGN confirming that
there was an easement allowing Off-Peak Travelcards and Cheap Day
Returns on the 09:26 train, as she was refusing to sell them before
09:30 (next train being at 09:41 at the time).
