Hello
On the 6th of December, I have used the bus (20) from Veldhoven, Strijpsebaan to Veldhoven MMC. It seems on the system that I have forgot to check out. I want to get a refund on the transaction because I have just used the but to Veldhoven MMC but I was charged 8.00 Euros for the travel. I tried to request refund online but it says " You can only submit claims in Mijn NS for transactions in which NS was the carrier.". I do not understand what is the problem here. Can you help me get a refund ?
