Q: received photo book with error

Did you preview it before sending and does the printed copy match the  saved preview?  Preview a print project in Photos, iPhoto, or Aperture to avoid issues - Apple Support

Contact Apple at the contact link given in the ordr confirmation email or using the contact us link at the bottom of this page

If the error is Apple's then they will correct it - if it is your error then they probably will not

Sorry we are all just users exactly like you - you have to contact Apple not us

Contact Apple at the contact link given in the ordr confirmation email or using the contact us link at the bottom of this page

And you did not answer

Having a saved preview is the best way to verify what happened

LN

for the future I suggest you always preview using apple's suggestion and that you always save the PDF of the preview until the product is received

For this on contact Apple and see what they say

You need to review the book according to this Apple document in order to see what is being sent to Apple for printing: Preview a print project in Photos, iPhoto, or Aperture to avoid issues - Apple Support.

Keep that in mind for future orders.  Save the PDF file to compare with the printed version when it arrives. 

As Larry suggested call Apple and explain that happened.  They've been quite good at making amends in such situations.
