I got a phone call from one of those dodgy merseyside companies that pretend that they're publishing a book for charity and that you've sponsored it.
As luck would have it, just the previous week I had heard about it as a scam, and so hung up immediately.
As a warning to others, dont even engage them in conversation, because the next thing you'll know is a bill will arrive on your doormat for £3000, and it is one heck of a job to get them to go away.
The phoncall goes "Hello mr. xxxxx. I'm calling about the book you agreed to sponsor for charity X months ago, I'm so sorry it has taken such a long time to get back to you..."
