Your login profile has a CC number, an email, your name and your birthdate. All of these data elements are present in a reservation record. If any of them don't match, you are going to have an issue. Login and look at all your profile data. Is it all correct? Make any notes. Now, since you can find the reservation by entering Booking Number, Name, Birthdate, it appears that Name and BD are correct. Check that reservation data again. You might also consider resetting to a new password.
