It is about my Kindle -- in fact, Kindles. I have three Kindles at home. One for my son, and a Kindle DX and a Kindle 2 for me. I use Kindle DX for mostly for papers and articles, and Kindle 2 for my pleasure reading.
Although both my son and I really enjoy Kindles, we had defective screen problems with them. My son's Kindle showed black mark on the screen twice. Each time, Amazon sent a replacement immediately as a warranty service. However, the person who processed the second replacement made a mistake and charged for it. I called Amazon to ask them to cancel the charge. Instead of cancelling the charge, the person that I spoke to process it as a refund. The problem, however, that he refunded a wrong Kindle -- my Kindle, not my son's, which was bought using my school's account. So, they charged to my personal card and refunded to my school. God knows why he did it, but eventually, we sorted out this mess. Another Amazon person apologized for the inconvenience and I thought all the problems have been resolved.
