It also dosn't apply to offshore call centres, cause they use an international number which Britsih legislation dont apply to.

It's more the 'survey' call that can be dangerous.
They ask one or two innocuous questions like ' do you think the price of petrol is too high?' or 'should bank charges for overdrafts be regulated?'
then there is a lead in to one detail like 'I use TSB , but I'm thinking of changeing as they charged £xxx because '.
All they want is one piece of information.

Don't forget, being polite is a disadvantage.

Think Victor, and you won't go wrong.
