I am wary of complaining to Amazon because I heard that if you complain too many times, they will lock your account. For Kobo purchases, my standard well-oiled routine is to load the book onto the iPad, take screenshots of pages with errors and attach the image files to my Kobo customer service complaint. When I don't attach screenshots, the process takes longer because the usually lazy reps claim they cannot find the errors and ask me for further clarification. I find that when I submit a proper package with everything spelled out very clearly and unequivocally, I get a much swifter response.
I do get a cheerful refund whenever I complain since the errors are clearly not my fault, and I have thoroughly documented them. However, in most cases I would prefer to simply have an error-free book. I am not sure yet who the best person is to get that for me, so I settle for a Kobo refund so at least I myself am not out of pocket for a shoddy book
