I purchased a ticket through the NS app at 20:58. The payment was successfully deducted from my account, but the ticket did not appear in the NS app. I only received an email confirming the purchase. However, the ticket was still missing in the app, making it impossible to check in or out.
To continue my journey, I had to purchase another ticket at 21:03, paying again. This time, the ticket did appear in the app. As a result, I had to pay twice for the same trip because the first ticket did not show up in the app, despite the successful payment and email confirmation.What should I do for receiving the reimbursement?
