Hello.
A couple of years ago I was proposed by NS to switch to NS Flex for free. The abonnement would only imply the debiting after travels. Nothing to pay unless a travel took place. No discounts or special fares (this was before it became possible to travel with the bank card).
Now I have seen that since months I have been first debited 2,50€ a month and lately 5,60€ for a “NS Flex Dal Voordeel” abonnement that I have never requested. Could somebody explain how this occurred?
Thank you
