What the heck of BookDepository.co.uk - they are rubbish!!!

This is my order and it has been 3 working days but i still didn't receive it

I booked this book on Monday and now is Thursday. I am very upset at the moment because i ordered via online this book thought it was cheaper by 1 pound compared in Lab. So i thought it might be worth buying it via online. So i did!!! What the heck...i need this book for my research and i still didn't received it for FUCK SAKE!!!!!!! If i'd knew it, i will buy this book from the Lab and it's only 1 pound dearer. They have wasted my 3 days time and it's worth more then 1 pound!! SHIT THIS COMPANY!!!!!!!!
