I get few scam calls but the last two or three have been from people telling me that my roof needed repairing. I usually string them along, telling them that I’m happy they’ve called me as I’ve been trying to get someone to come and fix it for months. I then arrange for them to come to a vacant house in my village which is miles from anywhere. They don’t know my real address and I can sense their excitement at finding a victim. If I get bored, I ask them to hold on while I get a pen and see how long it is before they hang up.
