Pathetic online store service.

The most disappointing online store service. I placed an order on the 12/12 for books that my daughter wanted for Christmas. These books are in stock according to the online store. I checked online on Monday, under my account and the books are pending. So I emailed to find out the ETA of my order as the email and confirmation page stated 4-5 days. I get an email response today and they state my daughters christmas gift will only arrive on the 19/01. Are you people insane, why state that you have stock with an estimated delivery in 4-5 days!? False advertising and pathetic service. You have enough time to deliver before Christmas.
