Remember how I told you about the Telephone Preference Service? Well, it's been a while now, and I've not had a single cold call. BLISS.
I've just signed up with the Mail Preference Service as well, since I'm getting sick of receiving letters offering me low cost loans to get me in even more debt. Apparently this will take 3-6 months to get a significant impact, though. I've also registered the two most common previous owners I still get mail for (despite them not having lived at the address for well over two years) in the hope I'll stop getting spam mail for them.
