Don't fall for telephone cold calls from con artists who claim they can stop telephone cold calls – that's the message from consumer watchdogs.

Officers at Norfolk County Council's Trading Standards department say they have been made aware of a number of companies cold calling claiming to offer a 'service', with some charging one off fees and others charging ongoing monthly fees.

A spokesman said: 'It is extremely unlikely that any 'service' of this type can legitimately claim to be able to stop cold calls so any money paid is unlikely to achieve any benefit.

'We always advise never to buy items or agree to ongoing services when approached by a telephone cold call.'

People who have responded to such a call is urged to contact the Citizens Advice consumer helpline on 03454 040506.
