Literary Guild Literary guild book club Poor Customer Service Internet

I am a member of the literary Guild. The offer I received obligated me to 4 books over the next 2 years. I was sent a promotion email for free shipping and picked out two more books as I had previously ordered two others not long after I started my membership.  This purchase was placed because of a promotional email I received for Free Shipping with the purchase of 2 books.  So I placed the order. I was not charged for shipping for these books according to the email I received after purchase. I have a screenshot taken of the email which clearly shows 0.00 for shipping charges.

However; they have these BookSearch Plus books which are not supposedly member edition books towards your membership fulfillment. This is not clearly disclosed when you order a book or review books on their site. As a matter of fact, it shows "mem edition" with a price next to it. So you are led to believe these are books that would fulfill your membership obligation. No where next to any of these so called BookSearch Plus books is the word BookSearch Plus book mentioned.

 According to their policy #3 ( posted below this thread) I should " not " have received the free shipping option as that was a promotion valid through May 30th 2011 only and would exclude the BookSearch Plus items. As per the order and email receipt that I received ,no shipping costs were added to the total and no mention of the BookSearch Plus item.

If this is a BookSearch Plus item at the time of purchase, shipping costs "would" probably have been added to the total for that item since this order was placed in response to an email promotion and BookSearch plus items are excluded from online promotions. So by making this single book a BookSearch Plus book, they gave me the free shipping but then this book does not mean I have fulfilled my membership obligation. I wonder how often they do this to customers? 

 At the time period I purchased the book in question I do not believe it was BookSearch Plus item based on my ability to make the purchase without having to pay shipping costs. This seems to be in accordance with their policy of  #3 where BookSearch Plus items are not included in the on-line promotion or sale.

Literary Guild Policy: #3
3) If the book club is running a special promotion that you wish to take
advantage of by placing an order on-line, BookSearch PLUS items will not
be included in the on-line promotion or sale that the book club web site
is hosting during that time period.

I told them to cancel that book and they said they could not, even though it is a back ordered item. They just gave me information on how to return it. 
This is a reflection of their customer service, which is very poor. Rather than keep a happy customer and simply cancel that book shipment and let me choose another, they would prefer to lose a customer. Not sure I trust them if I were to return a book if it would be properly credited to my account so I might just keep the book that I don't want.
Either way, their response was not rude but they made no attempt to work with me to fix this issue. Very poor customer service and I want to let others know about this.
