Hi,
I have a question regarding my subscription and invoicing.
I always receive the invoice on the 10th day of each month.
On 10/06/2024, I changed my subscription from NS Flex Weekend Vrij to NS Flex Daal Vrij.
After changing my subscription, I received a new invoice, stating that I need to pay 78,88 euros for the period from 10/06/2024 to 08/07/2024.
I do not understand why I was not charged 119,95 euros, as my new subscription also includes free travel on weekends. Also, will I be charged again for the remaining amount? Can you please explain how this will be handled?
Thanks in advance.
