Make the Telephone Preference Service Effective

I posted this elsewhere before I knew there was a category for e-petitions. This is a petition aiming to stop the regular nuisance of marketing and scam telephone calls that afflict many of us, even if we are members of the Telephone Preference Service [TPS]. A recent 'Panorama' programme concluded that TPS must be made effective; and many of us think it could be made effective. If scam e-mails can be filtred, why not scam telephone calls? It won't happen, though, unless Parliament acts. The e-petition called 'Make the Telephone Preference Service Effective' on epetitions.direct.gov.uk/petitions/34069
