I am ashamed of myself for being so childishly spiteful but I just cancelled Amazon Prime as well as Kindle Unlimited (after many satisfactory years) because I had inadvertently deleted some books I had stored in "Collections," and could not find an answer or anyone to talk to about getting them "undeleted!"
I got hundreds of solutions instead, all generated by computer. Even under "contact us" I couldn't find a real person. It also took me an awful long time just to find an "unsubscribe!" Amazon keeps that feature well hidden. It's there but they make you look!
At the moment I am looking at Kobo and GooglePlay because I don't want to buy another book from Amazon! As I said, I don't like myself for being so vindictive, so be kind to me!
P.S. I should have added that it has cost me $ 150.00 so far to buy back some of the books I had in those deleted collections. I was trying to make room on my tablets because they were showing 3000 books read and unread but thought my precious collections ( Robert B. Parker's Spenser, Dick Francis, Alistair MacLean) would be left alone!
