SUE Nelson’s column (The Press, February 3) about unwanted tele-sales calls reminded me of a similar experience some ten or so years ago.

I received just such a phone call. It turned out the company phoning was attempting to sell double glazing.

I twigged early on what the call was about, but kept the person on the phone for over an hour and a half, by virtue of saying such things as “I am certainly interested in retaining heat in my home” and agreeing with them when they said to me: “Surely you would like to reduce the amount of money you spend on your heating bills and reducing the noise from external sources, etc.”

I could detect the tone of success in the sale’s persons voice rising as the call went on. The sales person thought they had a done deal, until I asked if I needed to contact my local council as I lived in a council property.

The phone was put down immediately by the caller. But I was quite comfortable in my warm council property (previously double-glazed by the council) laughing so much I nearly broke a rib or two.
