I have received an email from Ryanair asking me to pay a fee months after I booked my flight. As a result, I cannot see the booking or do anything with it in the official Ryanair page.

The flight was booked with eDreams and the message Ryanair sent me was by email. I have screenshot the Ryanair page that has this message:

• The email is valid and it is not a scam
• The screenshot is from the Ryanair page when I am trying to find my booking using the 6-digit reference
• I have paid for that return flight in November 2021 and the flight is in July

Is there anything legal I can mention to the Ryanair support? Or do I need to contact eDreams instead?
