If one of your trips is incomplete because of a missing check-in or check-out, we will charge a EUR 20 correction fee. After paying this fee, you can contact the OVpay customer service desk by phone to correct this: dial 0900-1433 on working days between 07:00 and 20:00, or on weekends and bank holidays between 10:00 and 16:00 hr. Make sure you have the following details ready: the reference number displayed on your bank statement (NLOV followed by 14 digits) and the total amount deducted. The excess amount will then be refunded within a few days.
