Since it's 23 minutes long, it took me a while to get around to listening to this recording. (via MarkCC) But when I did, I was amazed. It's well worth the listen, but at the same time it's infuriatingly frustrating. I found myself banging my head against the wall along with the caller.
Quick synopsis: Guy is travelling to Canada. Before leaving he calls Verizon wireless to check what the rate will be. He is quoted 0.002¢ per kilobyte. Just to be sure he asks the rep to repeat that it is 0.002 cents and not 0.002 dollars and to put it in writing. When his bill arrives, he finds he has been charged $0.002 per kilobyte. The recording is of what happens when he calls Verizon to complain.
