Many thanks to a blog reader from Great Waldingfield who has drawn my attention to the fact that the scam referred to on the blog at the end of October is actually very old news.
If you visit the Phone Pay Plus website (they are the people who regulate premium rate numbers) on http://www.phonepayplus.org.uk you will see that they actually closed this particular operation down two years ago. The scam did originate in Belize, but it turns out that the claim that calls cost £15 was wrong, and that a call to the number in question would have only(!) cost you £9 if you had been on the line for the maximum 6 minutes.
I have passed this information on to Babergh and am sorry if I have caused concern to any of you!
