Blatant disrespect and unfair customer experience.

There seems to be no care in the world for some of your customers with issues. I need to understand why someone paid the exact same amount of money on the exact same book, but had theirs delivered in two weeks and I have been waiting nearly two months now. I do not need you to tell me things I already know about lead times when I ordered the book. I ordered it on 21 Jan and it had a lead time of approx 18 days and was happy to wait. Expected deliver was 21 Feb. Then received delayed notification indicating book will be delivered 25th Feb. No further updates and when I logged onto the site, it indicated that expected delivery date is now 15 March, without any notice. To my surprise someone ordered the exact same book as I did, had a lead time of 11 to 13 days, order was placed on 14th Feb and delivered on 1 March. How in the hell did this happen? Do not say you will check with supplier, because I did not order from supplier, I ordered from you. If someone received their book before mine, it indicates that stock had arrived from the supplier to you, and from your warehouse, it was shipped to the other person who got theirs on 1 March. Please just send me the book. This is obvious unfair business practices. What did this person do to receive their book before me, when I placed mine almost a month earlier? I would like an explanation of how this happened. It was the exact same book, for 570. Then I would like to receive my order asap please. This is not cool and so disrespectful.
