Hello,
I had planned to travel from Heyendaal in Nijmegen to Sittard. However, I forgot to tap my OV card and ended up buying an E-ticket on the train. When I arrived in Roermond and tried to switch from an Arriva train to an NS train, I accidentally tapped my card on the Arriva device before realizing that I had already purchased an E-ticket.
I'm hoping you can advise me on what steps to take to get a refund for this mistake. I've already tried to check my journey history on the website, but the system wasn't able to show me anything.
