You may also contact customer service directly; they will also be able to tell you why you need to pay this amount. Usually, this is most easily done by phone, as they are available 24/7 at 030-751 51 55. You may also contact them by chat (click the link Chat with NS on this page) or by sending a message on Twitter or Facebook. You can find additional contact information on this page.
If you didn't have a Traject Vrij subscription, but you did rent a few OV bikes, then you are most likely paying for that. The costs for renting OV bikes are also withdrawn from your bank account.
