Just an update on my situation. Amazon gave me a £60 amazon gift card which I used to buy the Digital Deluxe edition of the game. It finished downloading 3 mins after midnight so was able to play for a while last night and some more this morning before work.
@CJT7777 kindly pointed me in the direction of Shopto who had the CE in stock £10 cheaper than amazon so I ordered the CE from Shopto last night and when I got the despatched email this morning I cancelled the Amazon CE order.
Amazon got what they deserved after hiding the fact that they could not fulfil their orders of CE's. When I was speaking with the supervisor on chat last night even though he had told me they didn't have a CE for me my order still showed as delivering today. So they deserved to have to give me £60 credit and lose my CE order.
