I would but i always forget to check what time i arrive at forest hill and note it down which you need to know to fill it out
It just seems a pain for a couple of quid with sending it off buy post, should be simplified and made totally online.... by the time i get home Im just glad to get home...should compensate us like they did in the old days 5% of your annual ticket, which at least negated the fare rise.

They should also give us use of reasonable use of public transport with our tickets to get back home as they do sometimes do when there has been a major issue, if more than 1 train is cancelled as it would ease the congestion and reduce the chaos at London Bridge.

As for trains been cancelled / delayed due to congestion... well I have the national rail app on the front screen of my phone and whenever i check my phone, trains are constantly cancelled / delayedthrough out the day even in the very quiet periods between 10 and midnight its defintely not congested then! Always feel sorry for the poor s*ds who have there pots 11pm trains cancelled!
So not sure how they explain all those delays and cancellations.

Its a total utter mess to be honest.
