It has come to my attention that some copies of the Indian edition of the Official Guide to the TOEFL were printed without a digital access code for the audio files and software. Those are supposed to be contained in an envelope at the back labeled “Digital Access Code.”
It may not be necessary, but if you email support, I recommend including the ISBN number of the book, as well as a picture of the book to prove that you bought a copy. Obviously a receipt would help too, but that could be tricky.
