I recently had a discussion on the Chat to cancel my subscription with NS.
I was informed that I had to cancel it manually before the 10th of September from an NS terminal.
However, I am not able to be in the Netherlands before the 10th. I asked them to change the date to extend it and they told me that was impossible.
Effectively the person cost me a month subscription. They acknowledged the fact and ignored me for 10 minutes. I believe they left the chat open so I would not be able to give them a bad review.
I downloaded the conversation but I am not sure where to forward it in order to report the bad service.
Please let me know how to procceed.
