So this week I have been dealing with a difficult situation as a buyer. I ordered a series of books online from various sellers via Amazon. They all arrived on time, and all appeared to be in the condition stated online. But as I started reading one, pages began to fall out, in chunks.
At first, I thought I had just pulled out a page on accident. With a used book, it could happen. But then, pages 15 – 32 fell out all at once. Annoyed, and not wanting to stop reading, I just glued the pages back in to the book. It worked, for a day or two. Then pages 116 -179 fell in to my lap one day. SIXTY-THREE PAGES!!! I was done and wanted my money back, but knew that meant returning the book and having to put a pause in reading the series.
But thanks to Amazon, I am now quite pleased with the situation. I emailed customer service to let them know that I was unhappy. Within a couple of hours, I had a response, personalized to my situation. Not only that, they had processed my refund before the end of the work day! Not only that, I get to keep the book. I have no problem paying nothing for a book that is falling to pieces.
Thank you Amazon, for quick and easy customer service!
