I would call nonsense on that.

If you notice a mistake with your booking after you have paid for your ticket(s), you can cancel your flight booking and claim a full refund without penalty, up to 24 hours from when you make the original booking.
Refunds under these circumstances can only be requested by calling our contact centres.
The following types of booking are not covered by this guarantee:
Bookings made for travel within 24 hours of booking.
Bookings where immediate payment is not required.
Package bookings or flights booked with hotels, car hire or experiences.
Just because you upgraded your tickets does not mean that there was not an error. It just means that you had not
noticed the error.
