I purchased Dal Voordeel(€5.10) subscription on 10 September. But I would like to change it to Weekend Vrij+weekday offpeak 40%off (€31.60+€3.10) because I travel far in the weekends. I haven’t taken a train yet since the subscription started so I haven’t used it yet. How can I change it? “Change subscription” page on mijn NS doesn’t allow me to change until 10 October.
Or if I cancel my Dal Voordeel subscription and get a new subscription in Weekend Vrij, can I get a refund for Dal Voordeel which I haven’t used yet?
