Went over to the neighbours house with wife in tow. Showed the neighbours the 'defaced' book (although they would have been aware of the sorry state of the book).
I should have known they weren't interested in replacing it, although apologetic. If the neighbour was sincere she would have offered to do so yesterday.
I cant blame the kids. One looks like a prepy & the other is even younger. The responsibility lies with the parents.
My avenue now is with auspost, if they were indeed the courier service. I wonder if they will pass the buck to Amazon & vice versa.
Edit: just realised the 2 torn pages whilst trying to separate them actually affects 4 pages (double sided). *slaps forehead*
