I pay for texrbok, no delivery 2 weeks later!

i ordered and paid for an essential textbook on Feb 12 2015 from [URL Removed] and still have not received it today the 28th of Feb 2015. I call numerous times, only to find out the book was delivered to the wrong address and I am still confused as to why I have to still be without a book i paid for while they try to track down the book via fedex and their possibly illiterate couriers. i was then assured that they had sorted out the mess telephonically and via twitter saying that the book will be delivered yesterday,27 Feb 2015, sometime after 16:00 and its now night time I'm still without a book, all stressed out and feeling like an idiot. i had suggested they refund me rather so that I can go to a bookstore physically and acquire the book but an agent made it clear that it won't be so easy for that to happen. so i pay for for goods, i don't receive said goods and I can't get my money back until they recover the goods and here i am losing valuable study time. how i do i make up for all the lost time, and get to study effectively under all this undue stress. there must be some legal recourse coz i feel cheated right now!
