Purchased tickets for travel from Alton to London including zones 1&2 for the underground. There is no barrier at Alton station so we entered the train. On arriving at Waterloo our tickets did not work at the barrier and we had to wait for a member of staff to prove we had the correct ones via my email confirmation! The tickets were then ‘not valid’ for the underground so to save further embarrassment we used out debit cards for the underground. On our return journey our tickets were accepted on the underground however not at Waterloo - meaning we missed out train home as we had again to ‘prove’ we had valid tickets even though the date of travel was clearly printed on them. There is no contact number for Trainline!!
