How long does it take to put up a cover image?

Having refused four times to accept that they had the incorrect cover artwork for my book 'The Gathering' Amazon finally accepted the fact and took the old artwork down. That was days ago and still they haven't managed to put the correct one up! How long does it take to post a cover image on a web-site? Here it is - in case they've lost it!

 

No wonder I lost faith when Goodreads sold out to them!
