Lesson learned folks, ask a second set of eyes to double check details, like DOB, PP # and esp Name before making that payment. Unfortunately airlines are bleeding money and I don't blame them. But here was another option if you wanted to save your 20 Euros:

As per Aegean Airlines 24-hour Cancellation policy, passengers can cancel a flight booked on Aegean Airlines within 24 hours of the purchase. Aegean Airlines will provide a complete refund of your ticket cost in case the booking was made a week or more prior to the departure date of your Aegean Airlines flight.
