Have been getting a call from these jokers almost daily for several weeks. Finally got to speak to someone today. This allowed me to do my favourite trick for any cold caller ... interrupt them early on in there spiel and simply say, "Hold on, it's not me you need to speak to, I'll just go and get them for you". I then shout out "Bob it's for you", then I say to the caller, "Hold on a minute, he's coming". I then simply place the phone on speaker and listen to them wait and try not to laugh at their repeated "Hello, are you there?". You can prolong it by going back every minute or so and saying, "Hold on, he's nearly here". You can keep them waiting 5 minutes or more sometimes. Brilliant. That really messes up their sales targets. They usually don't bother ringing back either. Double success :o)
