Not very good lurker
I had one the other day and once he said he was from a company I don't have an account for and asked me if I had a few minutes I said "No, and actually you shouldn't have my number as I am on the telephone preference service" He went totally quite and hung up after about 10 seconds.
Then remembered I am not any more as I have changed from BT to SKY for my line rental and felt even more smug. It does scare them.

I just say im not interested or 'no thanks' and hang up
I am actually old enough to know that telegrams don't really exist any more. They are trying to get me to give info about my neighbour who 'they can't deliver to'. SCAM writ large, methinks, or very dubious debt collectors. I wish they'd just fuck off, and I am registered with telephone preference but I still get at least 5 cold calls a week 
I wish I had the guts to do something like that!
