I ordered a used book from an Amazon seller on October 17, 2007. My credit card was charged within 2 days. I've ordered various used books from Amazon sellers and they've never taken longer than about 2 weeks to arrive. Because I had some time to spare before my half-semester class started, I did not request expedited shipping.
On November 4, I had not yet received either the book, a shipping notification, or any other communication from the seller. I was out of time for the book to arrive, so I decided I'd ask the seller to cancel the order, or if the book had already been shipped I'd wait for it to arrive and then return it, even if it meant losing some money on the transaction. So, I sent the seller a polite email explaining that since I had not received the book or a shipping notice, I'd like the order cancelled and the money refunded to my credit card.
Now, on November 13 I have not heard from the seller in any way, have not received the book, and have not had a refund on my card. What's my next step?
A) Try another email to the seller.
B) Contact Amazon to advise them of the issue.
C) Dispute the charge on my credit card.
Thanks in advance for the help!
