why does my ns flex not work

Hello, 

My NS Flex abonnement does not work. 

I had an unpaid invoice a couple of months ago therefore my subscription was canceled. I paid the open amount and ordered a new Ns Flex subscription on the 10th of March. I paid the subscription and received a confirmation via email as well. However on my ns card it says the payment Failed (which is not true, It has been charged to my bank account on the 10th of March already and also has not been refunded) 

But on my card it does not show.

Can you please help me ? 

Thank you very much and let me know if you need any further details or a proof of payment. 

Best regards 

Rachel Hintzen
