Dear,
On 4th of May 2023, I bought NS Flex Weekend Free with the discount price (26,1 euro/month). As I far as I understand, I will use this subscription for traveling in one month (from 4th of May to 4th of June). However, on 5th of May, I received an email from NS sending my invoice and I have to pay 2,63 euro. I actually don’t understand it. Can you help me figure it out?
Thank you for helping and I hope to hear from you soon.
Kind regards,
Quynh Anh
