Hello there,

I just subscribed to Altijd Vrij (€ 353.80) this morning. But when I’m back from work this evening from Utrecht Centraal Station to Zuid Station, a total of €8.10 still deducted from my OV Chipkaart.

My questions are:

• How it really works?
• Do I need to get a new extra OV Chipkaart as if it’s not link to my existing card?
• what should I do?

Thanks in advance for your help. 
 

Hey R Matthew. Welcome to the NS Community.

Assuming you've ordered this on a card you already had, you have to pick this up at a card machine. Have you done this? If not, this would still be paid like such. I'd recommend contacting our customer service to see what's going on here and get a refund if you're entitled to one.
