If things like the Telephone Preference Service are going to achieve anything, they need teeth. In this case it's a £5,000 fine for unsolicited calls when you've registered not to get them. A firm called Town and Country Cleaning has been calling us (even though I told them on the first call that we're with the TPS), so I've used http://www.tpsonline.org.uk/cgi-bin/tps_complaints.pl to register a complaint. The company blocks CLID so I can't give their number: I'm interested to see if a simple tactic like that can circumvent the system. Few of the companies that call - and thankfully it's not many - seem to know what the TPS is; or at least few of the people they employ to make the calls.
