For my American readers: Apparently you won’t find this number on their Web site, but Kevin Kelly has located this semi-secret number for a real human at Amazon customer support: 800-201-7575.
UPDATE: Champ asked if there was a contect number for Amazon Canada. A quick search brought me to this page, which indicates that the 7575 number is good for US and Canada. I stand corrected. That page led me to this page, which seems to be the bitter center of the Amazon customer service number universe.

Humans at Amazon, you say? How positively 20th century!
Any contact # for Amazon Canada?
Unfortunately I have no (free) access to this number from Germany and Amazon in Germany does not have a freecall-number, just an expensive 01805 (costs about 10cents a minute which is as much as 6 times! as much as a long distance call costs here and they don’t provide a “normal” phone-number so you have to pay those high rates – they are even getting money this way if you call them for support – a totally lack of support in Germany, but that’s unfortunately also usual here – Germany is a “service desert” mostly) – but I’m continously looking – maybe some day they are registering a free call number in Germany as well (even if I don’t think so). Greetings David.
PS: Please don’t be angry about my english, it’s not my native language, thanks.
