...granted it won't help the fact that not having the book may cause you to fail anything, but there is a buyer protection that will at least get you a refund. The second step states you could have filed a claim for item not received after the ETA date has passed. So why did you not file after the 24 hours like you stated in the report the site says it must be shipped? Then you may not have failed if this was resolved in time. Some sellers slack off..but sometimes a dispute claim wakes them up pretty fast.
..here are the steps..good luck..
What are the Guidelines for the Buyer Protection Policy?
When you
order on Half.com, we provide an estimated arrival date for each item
in your order. The vast majority of the items you order will arrive
within that timeframe. In rare instances, items will take somewhat
longer to arrive due to shipping carrier delays and other factors beyond
the seller's control. Because of this, we encourage buyers to contact
their seller through the Half.com Email Forwarding System. Most issues
can be resolved amicably via email between buyer and seller. A Buyer
Protection Claim cannot be filed until the seller has been contacted at
least once via the Email Forwarding System.
The "Contact Seller" button should be visible as soon as a buyer places an order.
The
"File Claim" button should be visible 2 working days after the "Contact
Seller" button has been used. Buyers may file a claim for "not
received" after the estimated arrival date has passed.
Buyers have a maximum of 60 days from the date of the order to file a Buyer Protection Claim. **Note: the
"Contact Seller" button must have been used first allowing for 48
business hours to have passed so that a claim can be filed by the 60th
day.
