I am ex-directory and a registered at the telephone preference service. If I ever get a cold call of any description the first thing I ask is where the person calling got the number from. If they answer that (half of them ring off at that point) I explain that I'm busy at present but if they'll give me their contact details I'll phone them back. Most are unable to do this for some reason. If they can give me their details I complain about them to the TPS.
