Now, solve this instance: Review: I needed to replace a lost CD set of the library CD book: Cruel and Unusual by Patricia Cornwell. The one I ordered from Amazon was listed as a CD set (not as a cassette set) so I ordered it. I received a Cassette set of the book and NOT a CD set of the book. I wrote (through Amazon) to the seller and their reply was that I received a CD set.The Librarians can vouch for what I received as I showed them the envelope and the contents within it. Even though it was my responsibility to replace the CD book (so I wouldn't have to pay the Library charge), I now had to give that job to the library. Need I say more?This time, and it's the first time, Amazon has a very disgruntled customer.Thanks for asking for the review. Maybe Amazon could check into this and prevent others from experiencing what I experienced.Sincerely,Sherry BohmP.S. Yes, my husband and I are still Amazon shoppers. We're just going to have to be more careful now.
