I have started getting these calls again and apart from blocking the numbers I'm not sure how to stop them. I now start off by saying 'give me the details then' and have got as far as being told it was in a Red Vauxhall Cavalier. 1) I haven't got a current licence and 2) I haven't had a car for at least 15 years - where do they get my number from? I'd love to know if anybody is or knows one of these callers and because they end up hanging up on me how do they make a living?
