Sent Poor Condition book & Advertised Very Good.

Advertised a book as being in Very Good…
Advertised a book as being in Very Good condition. Pages were literally falling out of it - not attached to the spine at all and the cover was beaten up and somewhat folded, so even if they hadn't noticed the loose paged it shouldn't have been listed as Very Good.

I contacted them about it, and they said they'd give me a refund if I shipped it back, despite me giving them a picture of the pages separated from the book. Why do they need the book back? 

Finally, they agreed to refund me 25%, which I accepted to avoid the PITA of returning the book and to avoid them using it to get someone else, which they clearly intended to do else why would they want an unsaleable book back?

Further, they told me "Please remove the return request, so we may refund you correctly". No, I won't abandon the only protections I have prior to getting the refund.

Avoid this company. They have the worst customer service imaginable.
