Hi I usually travel from Bussum Zuid to Barneveld Noord through Amersfoort Central and yesterday(20th June) while returning back from work place I forgot check out check in from blue train to NS and meanwhile we had a ticket collector. I realised that when he checked and informed the same to him, he mentioned I can check out in Bussum Zuid and it will be corrected without any issues.

But in the late evening yesterday I got an email about 50 euros fine.

I request refund of the amount other than my travel expense in that route yesterday.

You can check my history and this is the regular route and I just missed checkin/checkout but you can also look at my route access.
