My toddler was playing with my Kindle the other day, and he bought a £600 (yes, six hundred) volume of books. I was unable to refund them automatically, and when looking for help I was confronted with a "fuck off" contact page. After finding the option to talk to a human, I was put through within 5 seconds, and the woman had the item refunded in about 1 minute.
Was pleasantly surprised.
