I’m holding a NSFlex card with NS Flex Dal Vrij subscription (107.9 euro/month). The start date is on 27-08-2022. The billing invoice is on 26th of every month. However, I want to change my subscription to Dal Voordeel (5.6 euro/month) to be used from 28-01-2023 and so on.
Which date I should make a process on changing a subscription to avoid the unwanted charge? It should be on 26th Jan or 27th Jan?
Please help. I’m new to NS system and it’s confusing for me.
Thank you in advance.
